Pose Catalog

Interoperability crosswalk

There is no shared identifier for a named sexual position. This is the join table: every catalog position mapped to the folksonomy tag that denotes it, plus knowledge-base entities and attested historical names where they exist, with the loss written down wherever the mapping is not exact.

mappings in total

219 folksonomy, 35 knowledge base, 85 historical.

exact folksonomy tags

Of the 219 folksonomy mappings, this many denote the position and essentially only it.

189

broader folksonomy tags

Each covers this position and others, and states in writing what it discards.

168

only precise record

Of 219 positions, this many have no exact or close match in a machine-readable external vocabulary: no precise folksonomy tag and no knowledge-base entity. Historical attestations are counted separately, being names in a text rather than resolvable identifiers.

How to read a mapping

Relations follow the standard matching senses. Most folksonomy mappings are broader, because the folksonomy these models learned from organises by act, not by named position. A broad mapping is still useful for prompting, but only if you know what it threw away, so every one carries a loss statement.

exactThe identifier denotes this position and essentially only this position.
closeNear-equivalent, with a real difference recorded in the loss.
narrowerThe identifier denotes a subset of this position.
broaderThe identifier covers this position and others. The common case.
relatedAssociated, but neither equivalent nor hierarchical.
noneNothing in the vocabulary denotes this position.

Where the vocabulary collapses 36

These tags each cover several structurally distinct positions. This is the clearest statement of why a mapping is worth publishing: in the vocabulary the models were trained on, there is no way to ask for one of these positions rather than its siblings.

Folksonomy mappings 219

The image-board vocabulary that open adult checkpoints were trained on. Load-bearing for prompting, because these strings work directly on a booru-trained model. Ordered least precise first. Support tags reconstruct structure the primary tag discards, and are the reason a broad mapping can still produce the right image.

Position	Tag	Relation	Shared with	What the mapping discards
Criss-Cross + on_back, on_side, interlocked_legs, on_bed	no tag exists	none	0	Relation is none, so there is no mapping and therefore nothing for a loss statement to measure. The blank is deliberate rather than an omission: no live tag denotes two bodies crossed at the hips in an X, and the support tags rebuild the supine and side-lying pair and the interleaved legs but not the crossing angle that names the entry.
Cross Position + on_back, legs_up, on_side, on_bed	no tag exists	none	0	Relation is none, so there is no mapping and therefore nothing for a loss statement to measure. The blank is deliberate rather than an omission: no live tag denotes a supine partner and a side-lying partner meeting at the hips at a right angle, and the support tags rebuild the two postures and the raised legs but not the crossing angle that names the entry.
The Rainbow Arch + on_side, arched_back, lying, on_bed	no tag exists	none	0	Relation is none, so there is no mapping and nothing for a loss statement to measure. No tag names this opposed, head-to-toe side-lying union: a tag-name search for head-to-toe in any spelling finds nothing, 69 requires the genitals at each other's faces, and on_side was not taken as a broader primary because the head-to-toe orientation, which the record calls its identifying fact, has no tag at all. The support tags reconstruct only the shared posture and the arch.
Snow Angel + lying_on_person, on_back, on_stomach, on_bed	no tag exists	none	0	Relation is none, so there is no mapping and nothing for a loss statement to measure. No live tag names this end-for-end stack, the penetrating partner lying face down on the supine receiver with the head toward the receiver's feet: missionary requires the partners to face each other, reverse_missionary has no posts, and 69 is mutual oral with the genitals at each other's faces; its wiki extends it more loosely to other acts in the same position, but its examples keep a mouth or the chest on the partner's body, while here the pelvises meet. The support tags rebuild the stack and the supine and face-down pairing but not the reversal that names the entry.
T-square + on_back, on_side, legs_up, spread_legs, on_bed, vaginal	no tag exists	none	0	Relation is none, so there is no mapping and therefore nothing for a loss statement to measure. The blank is deliberate rather than an omission: no tag in the permitted vocabulary denotes this perpendicular side-lying arrangement, and the support tags reconstruct it only partially.
Butterfly (edge of bed) + on_back, legs_up, spread_legs, standing, on_bed, vaginal	missionary	broader	26	missionary records only that the receiver lies on their back and the partners face each other. It discards the edge-of-surface geometry that defines this entry, hips at the very edge of a bed or table so the pelvis clears the mattress, and the resulting height offset that lets the penetrating partner work standing rather than kneeling. the permitted vocabulary has no edge-of-bed, bed-edge or furniture-edge tag (verified absent; on_table is present but denotes being on a table, not at its edge), so support can only assert that one partner stands while the other is on a bed, never that the two meet at its edge.
Coital alignment technique + on_back, lying_on_person, on_bed, hug	missionary	broader	26	missionary covers the entire face-to-face penetrating-on-top family and discards everything that defines CAT: the penetrating partner riding high up the torso, the two pelvises stacked in direct contact, and the small rocking grind that replaces withdrawal-and-return thrusting.
Crab Embrace + knees_to_chest, folded, on_back, kneeling, on_bed	missionary	broader	26	missionary fixes only that the receiver lies on the back facing the partner, with a folded body named as one option among several, so it holds equally for flat, leg-locked and folded forms. It discards the defining fold, both legs contracted tight against the stomach with the pelvis rotated up, and the partner kneeling into the gap rather than lying over.
Deck Chair + sitting, leaning_back, arm_support, knees_up, kneeling, spread_legs, on_bed	missionary	broader	26	missionary fixes only that the receiver lies on their back facing the partner, and its wiki admits leg-locked, folded and legs-held forms alike. It discards the half recline that identifies this entry, the receiver propped at roughly forty-five degrees on the elbows or straight arms with knees bent and feet flat while the penetrating partner kneels between them, a torso angle the tag's lying-on-the-back wording contains only loosely. Only sitting, leaning_back and arm_support carry the recline; the reclining wiki prescribes sitting plus leaning_back when the lower back is unsupported, as it is here with the weight on the arms.
Dragon Turns + on_back, knees_up, spread_legs, on_bed	missionary	broader	26	missionary is the tag for the whole supine face-to-face family and is exact for the catalog's own missionary entry, which this record matches in any still frame. The one feature it discards is temporal: the counted alternation of shallow and deep strokes that the record treats as the definition of the way, and no still-image tag can carry a stroke count.
Fixing of a Nail + on_back, leg_lift, split, kneeling, on_bed	missionary	broader	26	missionary records only that the receiver lies on their back facing the partner, and its wiki's list of leg options (a leg lock, a folded body, or the legs held) never singles out one leg, so it spans the whole supine face-to-face family. It discards the asymmetric split that is the entire content of this entry: one leg carried up toward the head while the other stays stretched flat along the surface, with the pelvis rotating to follow the raised leg. leg_lift and split restore that shape as a posture only.
Half-Pressed Position + on_back, knee_up, outstretched_leg, kneeling, on_bed	missionary	broader	26	missionary fixes only that the receiver lies on the back facing the partner and holds for any leg arrangement, from flat to folded. It discards the deliberate asymmetry that defines this entry, one leg extended along the bed while the other is drawn up to the chest, with the twist it puts through the hips, and the partner kneeling rather than lying over; knee_up and outstretched_leg restore the two legs only as separate postures.
Legs on shoulders + on_back, legs_up, vaginal, on_bed, boy_on_top	missionary	broader	26	missionary fixes only that the receiver lies on their back and that the partners face each other; it does not itself fix which partner is above (that is carried by the boy_on_top support). It discards the shoulders as the support point for the raised calves, the pelvic tilt and added depth that are the entire reason for the variation, and the deckchair form with the legs draped over the elbows. No replacement exists: there is no legs_on_shoulders tag, and the permitted vocabulary's only shoulder tags are carrying_over_shoulder, sitting_on_shoulder, grabbed_breast_over_shoulder, butterfly_on_shoulder, standing_on_shoulder, licking_shoulder, standing_on_another's_shoulder and standing_on_another's_shoulders, none of which is legs resting on a partner's shoulders. The support point is therefore unreconstructible from the crosswalk.
Lifted Missionary + on_back, hips_in_air, hands_on_another's_hips, arched_back, kneeling, on_bed	missionary	broader	26	missionary fixes only that the receiver lies on their back facing the partner, and its wiki admits leg-locked, folded and legs-held forms, so it covers the catalog's missionary, widely-opened and the-gap entries as readily as this one. It discards the defining support: the pelvis carried clear of the surface in the kneeling partner's two hands with nothing else under it, so the angle can change through a take, which hips_in_air and hands_on_another's_hips restore only as raised hips and a grip. anvil_position was passed over although its wiki sets an upturned pelvis apart from missionary, because the same wiki makes it a milder form of the piledriver, whose legs fold back, while this entry is a hand-held lift with the lower back arched.
Monkey's Attack + legs_on_another's_shoulders, folded, hips_in_air, kneeling, on_back, on_bed	missionary	broader	26	missionary spans the supine face-to-face family and admits a folded body without requiring one. It discards both of the receiving partner's legs carried up onto the kneeling partner's shoulders and the fold deep enough to lift the hips clear of the surface. legs_on_another's_shoulders, folded and hips_in_air restore the leg placement, the fold and the lift in support.
Phoenix Soars + squatting, on_back, knees_up, on_bed	missionary	broader	26	missionary spans the supine face-to-face family and says nothing about the upper partner's stance. It discards the penetrating partner squatting on the balls of the feet instead of kneeling or lying, and the clear vertical gap between the two torsos that the record treats as identifying. squatting restores the stance; nothing records the gap.
Pressing Position + knees_to_chest, legs_together, on_back, boy_on_top, on_bed	missionary	broader	26	missionary fixes only that the receiver lies on the back facing the partner, and its wiki admits a leg lock, a folded body or held legs alike, so the same tag already carries the catalog's yawning, legs-on-shoulders and splitting-bamboo entries. It discards the shape that defines this entry: both thighs drawn up closed against the chest and held there while the partner works over them, trading depth for pressure. knees_to_chest restores the fold and legs_together the closed thighs, each only as posture.
The Ram's Thrust + on_back, kneeling, legs_up, holding_another's_legs, on_bed	missionary	broader	26	missionary records only that the receiver lies on their back facing the partner, and its wiki lists the penetrating partner holding the partner's legs as one option beside a leg lock or a folded body, so it does not single out this entry's grip. It discards the identifying detail: both of the receiver's legs gathered under the arms of a partner kneeling upright and driving forward from the hips. holding_another's_legs and kneeling restore the grip and the posture separately, but no tag places the legs under the arms.
Reclining Lotus + on_back, crossed_ankles, knees_apart_feet_together, kneeling, on_bed	missionary	broader	26	missionary records only that the receiver lies on their back facing the partner, so it spans the whole supine face-to-face family and discards the folded lotus shape that defines this entry: the ankles crossed with the knees dropped wide in external rotation, the seated lotus laid down. crossed_ankles and knees_apart_feet_together restore that shape as a leg posture; lotus_position and indian_style cannot carry it, since both wikis define a sitting position.
Rising Position + legs_up, outstretched_legs, legs_together, on_back, kneeling, on_bed	missionary	broader	26	missionary fixes only that the receiver lies on the back facing the partner and holds for every leg arrangement, including the catalog's yawning entry with the legs spread in a V. It discards both legs raised straight to the vertical with the knees extended and the ankles together, and the partner kneeling close against them. legs_up, outstretched_legs and legs_together restore the raised, straight, closed legs only as posture, and kneeling says that the partner kneels but not that the kneel is close against the raised legs.
Splitting the bamboo + on_back, holding_another's_leg, vaginal, on_bed	missionary	broader	26	missionary spans the whole supine face-to-face family with any leg configuration, flat, leg-locked, folded, both legs held, and discards two things. The asymmetric shape (one leg raised to the penetrating partner's shoulder while the other stays extended along the bed) is only partly recovered by the singular holding_another's_leg; the permitted vocabulary's symmetric leg tags cannot help, since legs_up requires "both legs... thrust upward into the air". And the periodic alternation of which leg is raised, the motion that names Venudaritaka, has no tag at all: danbooru's leg vocabulary is entirely static-posture, so nothing in the permitted vocabulary encodes a repeating swap between two mirrored postures.
Stopperage + pillow, on_back, knees_up, spread_legs, on_bed	missionary	broader	26	missionary records only that the receiver lies on their back facing the partner, and the record itself says that without the wedge the figure is just a missionary. It discards the cushion under the hips that tilts the pelvis up while the shoulders stay flat, and the knees drawn up, which together shorten the working depth on purpose. No tag places a pillow under the hips (verified absent), so pillow in the support set asserts only that one is in frame, not where it sits.
Tabletop + on_table, on_back, legs_up, spread_legs, standing	missionary	broader	26	missionary records only that a person lies on their back with the partners facing each other, and it is the same tag the catalog's butterfly entry carries for its edge-of-surface geometry. It discards the waist-height table or counter that sets the receiving pelvis at the standing partner's hip, along with the partner standing at its edge, and because the tag requires lying on the back, the form propped up on the elbows is only partly inside it. The support tags on_table and standing carry the surface and the standing partner, but no live tag marks the edge of a table.
The Frog + m_legs, on_back, squatting, on_bed	missionary	broader	26	missionary records only that the receiver lies on their back facing the partner; its wiki names a leg lock, a folded body or held legs only as options and fixes no leg shape for either partner, so it spans the whole supine face-to-face family. It discards the two features this entry pairs: the receiver's heels drawn in to the buttocks with the knees falling wide, and the penetrating partner squatting into the space rather than kneeling or lying over. m_legs restores the first closely and squatting the second, but no tag joins them into one arrangement.
The Gap + on_back, hips_in_air, pillow, kneeling, on_bed	missionary	broader	26	missionary fixes only that the receiver lies on their back facing the partner, and its wiki admits leg-locked, folded and legs-held forms, so it covers the catalog's missionary, stopperage and lifted-missionary entries as readily as this one. It discards the cushion wedged under the sacrum with the shoulders kept flat, the visible gap under the lower back that names the position, which hips_in_air and pillow restore only as raised hips and a pillow, not as the gap itself. anvil_position was passed over although its wiki sets an upturned pelvis apart from missionary, because the same wiki makes it a milder form of the piledriver, whose legs fold back, and this entry keeps its shape with the legs lying flat.
The Pump + on_back, legs_up, spread_legs, standing, holding_another's_legs, bedside, on_bed	missionary	broader	26	missionary fixes only that a person lies on their back facing the partner, and it is the tag the catalog's butterfly entry already carries for the same hips-at-the-edge geometry, so this entry and butterfly cannot be told apart at the primary tag. It discards the hips placed right at the mattress edge and the penetrating partner standing on the floor at a lower plane, which is the whole source of the leg drive, and standing_sex cannot carry that partner because its wiki rules out a receiver lying on their back while the partner stands. standing, bedside and on_bed restore that one partner stands near the edge of a bed while the other lies on it, though bedside, whose wiki reads near the edge of a bed, does not place the hips at the mattress edge, and holding_another's_legs, which the missionary wiki names, pins the most common working form.
The Seducer + hands_on_another's_knees, spread_legs, kneeling, on_back, on_bed	missionary	broader	26	missionary covers every supine face-to-face union, and its wiki names holding the partner's legs only as something the position may involve. It discards the hold that defines this entry: the kneeling partner's hands at the receiving partner's knees, keeping the thighs apart so the receiving partner stays relaxed instead of holding the position open. hands_on_another's_knees restores the hand placement, but no tag records that the hold carries the load.
The Waterfall + on_back, head_back, kneeling, spread_legs, bedside, on_bed	missionary	broader	26	missionary fixes only that the receiver lies on their back facing the partner, with any leg arrangement. It discards the head and shoulders hanging over the edge of the bed with the neck extended backward, the inversion that is the whole point of this entry. No live tag names a head hanging past a bed edge, so bedside restores only the edge and head_back only the tilt of the head.
Turtle Rises + knees_to_chest, folded, kneeling, on_back, on_bed	missionary	broader	26	missionary spans the supine face-to-face family and admits a folded body without requiring one. It discards the compact fold that defines this entry, the knees pushed against the chest with the lower body drawn in tight, and the fact that the kneeling partner's weight rather than the receiving partner's arms holds it shut. knees_to_chest and folded restore the fold but not which body holds it.
Widely Opened + on_back, arched_back, boy_on_top, on_bed	missionary	broader	26	missionary fixes only that the receiver lies on the back facing the partner, so it carries the catalog's whole supine family, legs-on-shoulders and yawning among them, on the same footing. It discards the tilt that defines this entry, the head and shoulders lowered and the hips raised toward the partner above, which arched_back restores only as a bend of the spine. anvil_position names the tilt but cannot stand in: its wiki also asks for the legs spread wide on the floor, and the tag is already exact for the catalog's anvil entry, where a kneeling partner lifts the hips.
Yawning position + wide_spread_legs, legs_up, on_back, kneeling, on_bed	missionary	broader	26	missionary covers the whole face-to-face supine-receiver family, including the chest-to-chest, coital-alignment and folded mating-press forms; it does not encode the wide V of raised, spread legs or the penetrating partner kneeling upright between them rather than lying over the receiver.
Cross Double Penetration + straddling, on_back, kneeling, leaning_to_the_side, on_bed	double_penetration	broader	12	double_penetration records only that two penetrations happen at once and says nothing about where the partners are placed, so it covers this entry and the catalog's in-line stack alike. It discards the crossed geometry that defines this entry: the receiver astride a supine partner but turned off that partner's axis, and the second partner kneeling well off to the side at a clear angle to both, which is what frees the two partners to move independently. No live tag names an off-axis placement, so the crossing angle is carried by this statement alone.
Double penetration (DP) + group_sex, girl_on_top, anal, vaginal, on_bed	double_penetration	broader	12	The tag records only that two penetrations occur simultaneously. It also covers the catalog's double-vaginal, double-anal, standing-sandwich, spoon-dp and dp-reverse entries, and it does not encode the canonical stack of a rider leaning forward over a supine partner with the second partner kneeling behind.
Bridged Double Penetration + arched_back, on_back, girl_on_top, kneeling, sandwiched, on_bed	double_penetration	broader	12	double_penetration records only that two penetrations happen at once, in two of one person's orifices or two in the same one, by partners or by objects, and its wiki counts the mouth among the orifices, so it spans spitroast, toy, double-vaginal and double-anal cases as well as every stacked arrangement, including the catalog's double-penetration, dp-reverse, spoon-dp and standing-sandwich entries. It discards the bridge that defines this entry: the receiver arched over the supine partner on the feet and shoulders with the pelvis lifted clear as the high point of the body, the working gap the arch opens between that pelvis and the base partner's body, and the third partner kneeling at the open end.
Folded Double Penetration + lying_on_person, on_back, legs_up, m_legs, kneeling, sandwiched, on_bed	double_penetration	broader	12	double_penetration records only that two penetrations happen at once, in two of one person's orifices or two in the same one, by partners or by objects, and its wiki counts the mouth among the orifices, so it spans spitroast, toy, double-vaginal and double-anal cases as well as every stacked arrangement, including the catalog's double-penetration, dp-reverse, spoon-dp and standing-sandwich entries. It discards everything this entry adds: the receiver lying back face up along the supine partner's body, both knees drawn up and held wide in the fold that opens both entry points at once, and the third partner kneeling at the open end.
Piledriver Double Penetration + piledriver_(sex), folded, squatting, kneeling, on_bed	double_penetration	broader	12	double_penetration records only that two penetrations happen at once and carries no posture, so it covers lying, seated and carried doubles as readily as this one. It discards the inversion that defines this entry: the receiver up on the shoulders with the hips raised and the legs folded back, one partner squatting above and entering downward while the second works from the side. piledriver_(sex) in the support set restores the inverted core of the two-person form but not the second partner.
Prone Double Penetration + prone_bone, on_stomach, human_stacking, sandwiched, lying_on_person, on_back, on_bed	double_penetration	broader	12	double_penetration records only the two simultaneous penetrations and carries no posture, so it covers this entry and the catalog's sandwich-dp, which the seed builds from the same three base postures, on identical terms. It discards the flat prone build that the record names: the receiver face down along a supine partner with the third partner above and behind, all three spines roughly parallel. prone_bone in the support set restores the face-down rear entry, but no live tag separates this record from sandwich-dp.
Reverse DP (leaning back) + reverse_cowgirl_position, girl_on_top, spread_legs, anal, group_sex, on_bed	double_penetration	broader	12	double_penetration records only that two partners occupy two orifices and discards the arrangement that names this position: the receiving body reclined back against the supine partner and opened frontally, rather than folded forward onto the partner beneath as in conventional DP.
Seated Double Penetration + reverse_upright_straddle, sitting_on_lap, front-to-back, sitting, kneeling, on_chair	double_penetration	broader	12	double_penetration records only the two simultaneous penetrations and fixes no posture or surface, so it covers the catalog's lying, carried and inverted doubles alike. It discards the seated build that defines this entry: one partner sitting on furniture with the receiver lowered into the lap facing away, and the second partner kneeling in front, with the seat carrying the weight.
Suspended Double Penetration + suspended_congress, sandwiched, standing, hands_on_another's_thighs, front-to-back	double_penetration	broader	12	double_penetration records only the two simultaneous penetrations and carries no posture, and it is the tag the catalog's standing-sandwich already holds for this same carried build. It discards the airborne arrangement that defines this entry: the receiver held clear of the ground between two standing partners, one carrying under the thighs from the front and one taking the weight from behind. The support set restores the front carry and the between-two placement, but not the rear partner's share of the load.
Wheelbarrow Double Penetration + wheelbarrow_pose, hands_on_ground, holding_another's_legs, standing, sex_from_behind, on_back	double_penetration	broader	12	double_penetration records only the two simultaneous penetrations and carries no posture, so it covers the catalog's lying, seated and carried doubles alike. It discards the barrow hold that defines this entry: the receiver held horizontal on the hands with the legs carried by a standing partner behind, and the third partner working from beneath at the front. wheelbarrow_pose in the support set restores the hold but not the partner beneath.
The Sandwich + sandwiched, human_stacking, lying_on_person, on_back, sex_from_behind, on_bed	double_penetration	broader	12	double_penetration records only that two orifices are penetrated at once, or one orifice by two, and its wiki gives "sandwich" as a general nickname for every such case. It discards the lying three-layer stack that defines this entry: the receiving partner face down along a supine partner, the third partner above and behind in a plank or kneeling astride, and nobody carrying weight. The tag already covers the catalog's double-penetration, dp-reverse, standing-sandwich and spoon-dp entries in the same way.
Spoon DP (side-lying sandwich) + spooning, on_side, group_sex, anal, vaginal, on_bed	double_penetration	broader	12	The tag captures the two simultaneous penetrations but none of the geometry: it does not encode that all three participants are lying on their sides, with one partner spooning from behind and one facing from the front.
Standing sandwich (DP carry) + carrying, suspended_congress, group_sex, standing, anal, vaginal	double_penetration	broader	12	double_penetration encodes only that two orifices are penetrated at once and says nothing whatever about posture, so it equally covers lying, seated, kneeling, spitroast and toy-based DP, and by its own text it even covers one orifice taking two objects. It discards the defining architecture of this entry: two standing load-bearing columns with the receiver lifted clear of the ground and held airborne between them (support_surface partner_supported), the front partner carrying face-to-face while the rear partner presses in from behind. That architecture is recoverable only by reading `carrying`, `suspended_congress` and `standing` together, and no single emitted tag states it.
Froggy Style + squatting, spread_legs, kneeling, on_bed	sex_from_behind	broader	8	sex_from_behind encodes rear entry and nothing about posture: its wiki names doggystyle, standing doggystyle, prone bone, spooning and reverse cowgirl and closes on any other position from behind. It discards the receiver crouched forward on the feet with the hands down and the knees wide outside the elbows, the raised hip line that follows, and the partner kneeling behind, and squatting and spread_legs in the support set carry the crouch. doggystyle was passed over because its wiki confines it to a receiver on all fours or close to it and all_fours routes both knees off the ground to bear_position, while this entry carries its weight on the feet, and the name-matched froggy_style was passed over because it has no wiki page and its posts are also tagged all_fours, doggystyle and reverse_cowgirl_position, so its sense cannot be sourced.
Kneeling rear embrace + kneeling, hug_from_behind, grabbing_another's_breast, looking_back, vaginal, on_bed	sex_from_behind	broader	8	sex_from_behind covers all rear entry including bent-over, on-all-fours, prone and standing variants, and discards the specific feature here: both partners kneeling upright with both torsos vertical and the receiver's back flush against the penetrating partner's chest.
Magic Mountain + kneeling, legs_folded, leaning_forward, leaning_on_object, cushion	sex_from_behind	broader	8	sex_from_behind covers every rear-entry arrangement, and its wiki names doggystyle, standing doggystyle, prone bone, spooning and reverse cowgirl inside it. It discards the cushion bank built into a slope that carries the receiver's chest, the receiver kneeling forward onto that slope, and the penetrating partner kneeling behind and settled back onto the heels, so that both bodies are supported for a long hold. doggystyle was passed over because its wiki rules it out unless the receiver is on all fours or close to it, and here the chest rests on the bank rather than on the hands.
Over the Edge + lying, standing, bedside, on_bed	sex_from_behind	broader	8	sex_from_behind encodes only rear entry, and its wiki names doggystyle, standing doggystyle, prone bone, spooning and reverse cowgirl inside it and closes with any other position from behind, so it covers every rear arrangement on or off a surface. It discards the edge geometry that defines this entry: the receiver lying face down with the torso on the bed and the hips out past the edge, legs descending toward the floor, and the partner standing behind at that height. bedside restores only nearness to the edge of the bed, and no live prone tag places the hips beyond it, since prone_bone and on_stomach both want the crotch down flat on the surface, while bent_over_furniture fits only the feet-on-the-floor variation, where the receiver stands bent over the bed.
Pearly gates + lying_on_person, girl_on_top, on_back, spread_legs, on_bed	sex_from_behind	broader	8	sex_from_behind encodes only rear entry and nothing about posture, so it covers doggystyle, standing doggystyle, prone bone, spooning, reverse cowgirl and, by its own closing clause, any other rear position. It discards the entire geometry of this entry: the penetrating partner supine underneath, the receiver reclined flat along their chest spine-to-chest with both faces to the ceiling, and the thrust arriving from below rather than from behind an upright back. The face-up stack survives only in the `lying_on_person` support tag, and the receiver-on-top polarity only in `girl_on_top`.
Praying Mantis + kneeling, arms_up, front-to-back, behind_another, on_bed	sex_from_behind	broader	8	sex_from_behind encodes only rear entry, and its wiki names doggystyle, standing doggystyle, prone bone, spooning and reverse cowgirl inside it and closes with any other position from behind, so it already carries the catalog's kneeling-rear-embrace entry, the same two upright kneeling bodies without the raised arms. It discards that both partners kneel with both spines vertical and, above all, the receiving partner's arms raised overhead or folded high, the tall narrow silhouette that names the position. kneeling and front-to-back restore the upright stacked kneel only as separate postures, and arms_up restores only the overhead form of the arms, not the arms folded high across the chest.
Sofa Brace + kneeling, standing, leaning_on_object, couch	sex_from_behind	broader	8	sex_from_behind covers every rear-entry arrangement and fixes no posture or furniture. It discards the receiver kneeling on a sofa seat and folded forward over the back or the arm with the chest supported, which is the whole content of this entry. bent_over_furniture was passed over because its wiki routes through bent_over, which requires standing, so it fits only the feet-on-the-floor variation and not the kneeling default.
Standing rear press (against wall) + standing_sex, against_wall, standing, vaginal	sex_from_behind	broader	8	sex_from_behind covers every rear-entry arrangement, with doggystyle, standing doggystyle, prone bone, spooning and reverse cowgirl all named inside it by its own wiki, and most of those are on the ground. It drops that both partners are standing and nearly upright, the wall as the bracing plane, and the receiver's hands planted flat against it, which together supply both the support and the profile framing plane this shot is built on.
The Hinge + kneeling, leaning_back, arm_support, on_bed	sex_from_behind	broader	8	sex_from_behind encodes only rear entry, and its wiki names doggystyle, standing doggystyle, prone bone, spooning and reverse cowgirl inside it, so it also covers the catalog's upright kneeling-rear-embrace. It discards that both partners kneel and that the front partner leans back about thirty degrees onto locked arms with the torso opened away from the body behind, the hinge that gives the position its working angle; leaning_back and arm_support carry the lean, though leaning_back's wiki names standing or sitting figures rather than kneeling ones.
Bulldog + squatting, all_fours, sex_from_behind, vaginal, on_bed	doggystyle	broader	6	doggystyle covers all rear entry onto a partner on all fours, and is the tag the catalog's own doggy-style entry owns; it discards the defining detail that the penetrating partner is in a deep squat with feet planted outside the receiver's legs rather than kneeling, and with it the steep downward stroke angle.
Cowgirl (woman on top) + girl_on_top, on_back, vaginal, on_bed	cowgirl_position	broader	6	cowgirl_position denotes the whole facing-forward rider family: the wiki fixes only that the penetrating partner is lying down and the receiver straddles them face-on, saying nothing about the rider's torso angle. It therefore does not separate this upright kneeling-astride default from the catalog's own prone-cowgirl, cowgirl-leaning-forward and leaning-back-cowgirl entries, all of which fall inside it. Torso angle is the discarded feature and the permitted vocabulary cannot restore it: upright_straddle is the only candidate and its wiki requires the straddled person to be "sitting upright", not lying down, so no pool tag pins an upright rider over a supine partner. Containment is also imperfect in the other direction: riding while squatting on planted feet is routed out of the tag to squatting_cowgirl_position, so that listed variation of the entry sits outside the tag rather than beneath it.
Cowgirl, leaning forward + girl_on_top, straddling, hands_on_bed, vaginal, on_bed	cowgirl_position	broader	6	cowgirl_position fixes only that the receiving partner straddles a supine partner while facing them. It spans the rider's torso angles from bolt upright through leaning back, and it discards the forward-folded torso with the hands braced on the partner's chest or on the bed beside their head, which is what defines this variant.
Doggy style + all_fours, kneeling, on_bed, arched_back, vaginal, sex_from_behind	doggystyle	broader	6	doggystyle is the family tag for kneeling rear entry, carried by the compressed turtle fold and by multi-receiver line-ups alike, and the permitted vocabulary's standing_doggystyle child implies it; the tag therefore drops the one-on-one pairing and the receiver propped up on hands and knees at full working height that define this archetype.
Double Spit Roast + all_fours, doggystyle, kneeling, standing, side-by-side, shared_bed, on_bed	spitroast	broader	6	spitroast describes a single front-and-back double team, one person in between performing oral sex or paizuri at one end while penetrated from behind at the other, and it is the tag the catalog's spit-roast, spitroast-lying and eiffel-tower entries already carry. It discards the second team working alongside on the same surface and the matched alignment of the two triangles, mirrored or running the same way, which is the entire proposition of this entry. side-by-side and shared_bed in the support set restore only that the bodies are next to each other in one bed, not that they form two matched groups.
Eiffel Tower + group_sex, fellatio, sex_from_behind, all_fours, grabbing_another's_hand, on_bed	spitroast	broader	6	spitroast covers any front-and-rear double team. It drops the raised inside arms and the clasped hands above the receiver back, the single gesture that names the Eiffel Tower and closes the composition into its arch silhouette. That gesture is carried only by the support tag grabbing_another's_hand, which is itself undocumented.
Fire Hydrant + all_fours, leg_lift, sex_from_behind, kneeling, on_bed	doggystyle	broader	6	doggystyle covers the whole all-fours rear-entry family and is the tag the catalog's doggy-style entry carries, and that entry's own description lists one leg raised among its variations. It discards the single knee lifted out to the side with the hip opened to about ninety degrees and the pelvis tipped with it, the asymmetry that names this entry, although the tag still holds because all_fours needs at least one hand and one leg on the floor. leg_lift in the support set carries the leg lifted away from the planted one.
Fishes Interlock + interlocked_legs, sitting_on_person, on_back, on_bed	cowgirl_position	broader	6	cowgirl_position covers the facing ride over a supine partner at any torso angle and asks only that the receiving partner straddle the partner below. It discards the interlock this record treats as defining, the receiving partner's legs alternating with the partner's instead of sitting outside them, which keeps the pelvises tighter than a plain straddle. interlocked_legs carries the weave, but it is a thin posture tag with no sexual sense.
Kneeling Spit Roast + kneeling, seiza, front-to-back, on_bed	spitroast	broader	6	spitroast fixes only the two-ended structure, the person in between performing oral on one partner while penetrated from behind by another, and its wiki admits seiza and all fours as readily as standing, so it covers the catalog's all-fours spit-roast and its standing, seated and side-lying variants alike. It discards the upright kneel that defines this entry, the receiving partner held vertical between two kneeling partners instead of down on all fours, and no live tag restores it, since kneeling fixes only that the knees are down and the buttocks are off the ground, which admits any torso angle.
Cowgirl, leaning back + girl_on_top, straddling, arched_back, on_back, sex, on_bed	cowgirl_position	broader	6	cowgirl_position covers the entire face-to-face ride, upright, folded forward onto the partner's chest, and this backward-reclined variant alike; it discards the reclined torso and the hands braced behind on the partner's thighs, and with them the altered penetration angle and the fully opened front of the rider.
Leapfrog + top-down_bottom-up, sex_from_behind, arched_back, looking_back, on_bed	doggystyle	broader	6	doggystyle covers the whole rear-entry-on-knees family and does not distinguish this chest-and-forearms-down, hips-high variant from the base hands-and-knees posture, discarding the steeper entry angle produced by the shoulder-low-to-pelvis-high spinal slope.
Mare's Position + straddling, sitting_on_person, on_back, on_bed	cowgirl_position	broader	6	cowgirl_position fixes only that the receiver straddles a supine partner while facing them, and holds equally for bouncing, grinding and leaning rides. It discards the entire content of this entry, the rider holding still while the pelvic floor does the work, which no documented tag carries: pussy_grip names a grip only by the visible pull on withdrawal, the opposite of a still hold. The support set can assert only a settled seat.
Prone cowgirl + girl_on_top, lying_on_person, breast_press, vaginal, on_back, hug	cowgirl_position	broader	6	cowgirl_position fixes only that the receiving partner straddles a supine partner while facing them. It does not constrain the receiver torso angle, so it covers the upright ride and this flat variant equally, discarding the defining chest-to-chest full-length contact and the small in-place grind that replaces vertical hip travel.
Side-by-side doggy + group_sex, all_fours, on_bed, sex_from_behind	doggystyle	broader	6	doggystyle reads as a one-on-one pairing; it discards the second receiving partner on all fours alongside the first and the single penetrating partner working down the line between them, which is the entire formation this record names.
Spit roast + group_sex, all_fours, fellatio, sex_from_behind, on_bed	spitroast	broader	6	spitroast records only the front-and-back double team: it is applied identically when the centre partner is side-lying (catalog spitroast-lying), standing, or bent over a surface, and it also covers the Eiffel Tower variant where the two outer partners clasp hands overhead. It does not encode this entry's centre partner on hands and knees.
Lying spit roast + on_side, fellatio, sex_from_behind, group_sex, on_bed	spitroast	broader	6	spitroast fixes only the two-ended arrangement of rear penetration plus oral to a partner in front, and is the tag the catalog's plain spit-roast entry owns; it discards the side-lying staging of the central partner, which is the single feature separating this entry from the standard all-fours spit roast.
Seated Spit Roast + reverse_upright_straddle, sitting_on_lap, leaning_forward, on_chair, standing	spitroast	broader	6	spitroast fixes only the two-ended structure, the person in between performing oral on one partner while penetrated from behind by another, and its wiki leaves the posture open, so it covers the catalog's all-fours spit-roast and its kneeling, standing and side-lying variants alike. It discards the seated base that defines this entry: the receiver sitting back into one partner's lap facing away and hinging forward to the standing partner, with the seated partner and the furniture beneath carrying the receiver's weight.
Standing Spit Roast + standing, bent_over, standing_doggystyle, standing_sex	spitroast	broader	6	spitroast fixes only the two-ended structure, the person in between performing oral on one partner while penetrated from behind by another, and its wiki leaves the posture open, so it is applied identically to the catalog's all-fours spit-roast, the side-lying spitroast-lying and the Eiffel Tower variant. It discards that all three partners stand, with the receiver hinged forward at the hips to meet the front partner, which is the single feature separating this entry from the ordinary spit roast where the middle partner kneels.
The Swing + straddling, leaning_back, on_back, on_bed	cowgirl_position	broader	6	cowgirl_position fixes only that the receiver straddles a supine partner while facing them, and it is the tag the catalog's cowgirl, prone-cowgirl and leaning-back-cowgirl entries already share. It discards what names the swing, the front-to-back rocking in place of a vertical rise and fall, which no documented tag carries, and the slight backward tilt of the torso, which leaning_back only approximates.
Tiger's Tread + top-down_bottom-up, sex_from_behind, kneeling, on_bed	doggystyle	broader	6	doggystyle covers the whole kneeling rear-entry family with the receiving partner on hands and knees, and its wiki admits postures only close to all fours. It discards the deep crouch that defines this entry: the receiving partner lowered onto the elbows with the chest dropped below raised hips, so the spine slopes steeply down to the shoulders. top-down_bottom-up restores that wedge, but no tag separates this record from the catalog's leapfrog, which has the same chest-down, hips-high shape.
Turtle + kneeling, legs_folded, sex_from_behind, on_bed, vaginal	doggystyle	broader	6	doggystyle covers the whole kneeling rear-entry family with the receiver propped on all fours at working height. It discards the collapse that defines the turtle: the seat sinking back toward the heels with the calves folded against the thighs and the chest coming down onto them, so the receiving body sits low and compact instead of arm-supported at hip height, and the thrust line drops accordingly.
Cunnilingus from Behind + all_fours, behind_another, kneeling, on_bed	cunnilingus	broader	5	cunnilingus names the act alone, oral stimulation of the vulva at any arrangement, and is the tag the catalog's cunnilingus-lying, cunnilingus-legs-up and sixty-eight entries already carry. It discards the rear approach that the record calls the only thing distinguishing this entry from the supine variants: the receiver on all fours with the giver low behind at hip height, lying or crouched. No rear-approach form turned up on Danbooru: the staged forms found, standing_cunnilingus and tachihanabishi, fix a standing receiver and a receiver propped stomach up in a crab-walk posture, so that arrangement rests on the support set.
Cunnilingus (legs raised) + knees_to_chest, legs_up, on_back, spread_legs, kneeling, on_bed	cunnilingus	broader	5	cunnilingus names only the act, oral stimulation of the vulva at any arrangement (seated, standing, from behind, inside 69), and discards the entire postural content of this entry: the supine receiver with knees folded toward the chest and pelvis tilted up, and the giver kneeling over that fold face-down to the lifted pelvis.
Cunnilingus (lying) + on_back, spread_legs, lying, on_bed, grabbing_another's_thighs	cunnilingus	broader	5	cunnilingus names the act alone and discards the arrangement: it does not record that the receiver is supine with knees raised and thighs parted while the giver lies prone between them with the mattress carrying both bodies, so it equally covers standing, facesitting and head-to-toe arrangements that the catalog holds as separate records (cunnilingus-standing, cunnilingus-legs-up, facesitting).
Cunnilingus, receiving seated + sitting, on_chair, spread_legs, kneeling, head_between_thighs, on_floor	cunnilingus	broader	5	cunnilingus names the act alone at any arrangement and is the tag the catalog's lying, legs-up and sixty-eight cunnilingus entries already carry; the staged forms found, standing_cunnilingus and tachihanabishi, fix a standing receiver and a receiver propped stomach up in a crab-walk posture, and no seated form turned up. It discards the seat that sets the working height and makes this the most comfortable oral position to hold: the receiver on a chair or seat edge with the hips forward and the legs open, and the giver kneeling on the floor between the knees.
Double Cowgirl + cowgirl_position, straddling, kneeling, on_back, on_bed	sitting_on_face	broader	5	sitting_on_face fixes only that one partner sits, straddles or squats on another's face, and its wiki says nothing of which way the sitter faces or of any second rider; it is the tag the catalog's facesitting, facesitting-reverse and ffm-ride-and-sit entries already carry. It discards the double mount that names this entry, a second partner riding the supine partner's hips at the same time, and the default with both riders facing the same way and the face rider kneeling, which is what separates it from ffm-ride-and-sit, where the riders usually face each other.
Double Facesitting + on_back, straddling, kneeling, sitting_on_person, on_bed	sitting_on_face	broader	5	sitting_on_face fixes only that one person sits, straddles or squats on another's face, so it covers the catalog's two-person facesitting and facesitting-reverse entries and the face-mounted half of ffm-ride-and-sit with the same string. It discards the second partner straddling the supine partner's hips at the same time, the two seats spaced along one supine body that make this the facesitting arrangement extended to three.
Entwined Cranes + indian_style, sitting_on_lap, arms_around_neck, face-to-face, on_bed	upright_straddle	broader	5	upright_straddle covers every face-to-face straddle of a seated partner, and the catalog already files the cross-legged form under it as lotus and the chair form as face-off. It discards the embrace the classical name points at: the receiving partner's arms around the partner's neck with the two heads held level and close. arms_around_neck and face-to-face restore the embrace and indian_style the cross-legged base.
Face-off (chair straddle) + on_chair, sitting_on_lap, straddling, vaginal	upright_straddle	broader	5	upright_straddle covers every face-to-face upright straddle including the floor-seated lotus; it does not record that the penetrating partner is seated on a chair or couch edge with the receiver's feet able to reach the floor for leverage.
Facesitting + cunnilingus, on_back, straddling, squatting, spread_legs, on_bed	sitting_on_face	broader	5	sitting_on_face is also applied to clothed, purely smothering or dominance instances where no oral contact occurs, and it does not record whether the sitter faces the partner's head (queening) or their feet.
Facesitting Circle + circle_formation, on_back, lying, straddling, on_bed	sitting_on_face	broader	5	sitting_on_face fixes only that one person sits, straddles or squats on another's face, and it is the tag the catalog's facesitting, facesitting-reverse and ffm-ride-and-sit entries already carry, so it reads as a single two-person mount. It discards the ring that defines this entry, several partners lying with their heads toward a common center while the one astride moves from face to face around it, which makes every place in the circle equivalent. circle_formation in the support set restores the radial layout, but nothing in the crosswalk records the movement around it.
Facesitting (reverse) + cunnilingus, on_back, kneeling, ass_focus, on_bed	sitting_on_face	broader	5	sitting_on_face fixes only that someone is astride another's face; it covers both orientations of the straddle and smothering with no oral contact at all, and it is the tag the catalog's plain facesitting entry already owns. What it discards is the head-to-toe orientation, the sitter pitched down the length of the body, sight line along the torso toward the feet, which is the sole discriminator against ordinary facesitting. danbooru has no reverse-facesitting tag and no participant-orientation vocabulary at all (face-to-face and facing_away are both absent from the permitted vocabulary), so this is recovered only obliquely: ass_focus marks the rear-forward presentation at the level of image composition rather than of participant orientation, and kneeling separates this entry from the squatting variant the plain facesitting row carries.
FFM ride and sit + cowgirl_position, girl_on_top, group_sex, on_back, on_bed	sitting_on_face	broader	5	sitting_on_face names only the face-mounted half of the double mount: it covers the catalog's ordinary two-person facesitting and facesitting-reverse entries with no penetration at all, and does not encode the second partner riding the supine partner's hips at the same time.
Lateral coital (side face-to-face) + on_bed, leg_lock, hug, vaginal	on_side	broader	5	on_side is a bare posture tag shared with spooning, solo lying and wholly non-sexual scenes; it records neither the face-to-face orientation, nor the interleaved legs, nor that penetration is occurring at all.
Lotus + straddling, sitting, hug, breast_press, vaginal	upright_straddle	broader	5	upright_straddle covers any face-to-face lap straddle, including the chair straddle the catalog files separately as face-off and kneeling-upright variants; it does not record the cross-legged seated base, the legs-wrapped mutual embrace, or the close grind rather than thrusting that define lotus.
Pounding on the Spot + sitting, leg_lock, mutual_hug, belly-to-belly, on_bed	upright_straddle	broader	5	upright_straddle covers every face-to-face straddle of a seated partner, the catalog's chair-based face-off and cross-legged lotus included, and its wiki lists a leg lock only as optional. It discards the clasp that defines this entry, both partners seated and wrapped together with the torsos in full contact, and the record's motion, rocking pressure with no withdrawal, which no still-image tag can carry.
Pretzel (pretzel dip) + straddling, holding_another's_leg, spread_legs, kneeling, vaginal, on_bed	on_side	broader	5	on_side records only that a character lies on one flank. Its wiki body is one sentence of general posture and its see-also list runs to curled up, fetal position and spooning, so the tag covers non-sexual side-lying and rear-entry spooning equally. It carries none of this entry's geometry: the penetrating partner kneeling astride the receiver's lower thigh, the upper leg lifted against them, or the face-to-face contact that separates the pretzel dip from spooning. the permitted vocabulary contains no face-to-face tag, so that axis is genuinely unreconstructible rather than merely omitted.
Reverse Spoon + face-to-face, leg_on_another's_leg, lying, hug, on_bed	on_side	broader	5	on_side records only that a character lies on one flank, so it covers rear-entry spooning and non-sexual side-lying alike, and it already carries the catalog's lateral-coital and pretzel entries. It discards the face-to-face orientation that is the whole reason for this entry, the single upper leg draped over the partner's hip, and the fact that penetration occurs at all. face-to-face restores the orientation only as a general posture, and leg_on_another's_leg puts the draped leg over the partner's leg rather than the hip.
Rocking Horse + on_chair, sitting, sitting_on_lap, straddling	upright_straddle	broader	5	upright_straddle covers any face-to-face straddle of a partner who sits upright, whether on the floor as in the catalog's lotus entry or on a chair as in its face-off entry. It does not record the chair as the load-bearing seat, the receiver's feet planted on the floor, or the forward and back rocking against the chair back that names this entry, so it cannot separate this record from face-off.
The Shoulder Ride + head_between_thighs, sitting_on_person, straddling, standing, holding_another's_legs	cunnilingus	broader	5	cunnilingus names the act alone, oral stimulation of the vulva in any arrangement, so it covers lying, seated, standing and facesitting oral as readily as this one. It discards the carry that defines this entry: the receiver seated across the standing partner's shoulders with the thighs either side of the head and the legs held, carried clear of the ground. The record names only oral contact between an MF pair and does not say which partner is carried, so the mapping assumes the carried receiver is the female partner.
Sixty-eight (68) + lying_on_person, girl_on_top, on_back, on_bed	cunnilingus	broader	5	cunnilingus names only the oral act and nothing about arrangement. It discards the whole identifying geometry of this entry: two supine bodies stacked head-to-toe with the receiving partner lying face-up along the giver's body, the stack running back-to-front rather than front-to-front, and the one-way direction that names the position against the mutual 69.
The Corkscrew + legs_together, outstretched_legs, standing, bedside, on_bed	on_side	broader	5	on_side records only that a character lies on one flank, so it covers spooning and non-sexual side-lying alike, and it already carries the catalog's lateral-coital and pretzel entries. It discards the edge staging and the closed legs that define this entry: the receiver at the edge of the bed with both legs together and extended over it, rotated to one side, and the penetrating partner standing alongside, and it does not record that penetration occurs at all. legs_together, outstretched_legs, bedside and standing restore those features only as separate postures.
The Fitter-In + interlocked_legs, leg_between_thighs, face-to-face, lying, on_bed	on_side	broader	5	on_side records only that a character lies on one flank, and its wiki's see-also list runs to curled up, fetal position and spooning, so it covers non-sexual side-lying and rear-entry spooning alike; it is already the tag of the catalog's lateral-coital and pretzel entries. It discards the face-to-face orientation and the full alternating weave, each thigh between the other's, that holds the pelvises together without either partner bracing and separates this entry from the simpler crossed-thigh positions. interlocked_legs and leg_between_thighs restore the weave as a leg posture, and face-to-face the orientation.
The Stairway + sitting_on_stairs, on_stairs, stairs, sitting_on_lap, straddling	upright_straddle	broader	5	upright_straddle covers any face-to-face straddle of a partner sitting upright, on a chair, a couch edge or the floor alike. It discards the staircase that makes this entry, the penetrating partner seated on a step with the feet two risers down and the receiver's feet lower still, which supplies the height offset a flat floor cannot. The stair survives only in the sitting_on_stairs, on_stairs and stairs support tags.
Twining Position + leg_on_another's_leg, lying, face-to-face, on_bed	on_side	broader	5	on_side records only that a character lies on one flank, so it covers non-sexual side-lying and spooning alike and already carries the catalog's lateral-coital and pretzel entries. It discards the face-to-face pairing, the receiver's thigh laid across the partner's hip that is the whole mechanism of this entry, and the fact that penetration occurs at all. face-to-face in the support set restores the facing, and leg_on_another's_leg restores the crossed thigh only as a general posture.
Butter churner + pelvic_thrust, vaginal, on_bed, legs_over_head	piledriver_(sex)	broader	4	The tag already carries the squat and the shoulders-down vertical fold, so the single feature this entry adds is manner: the vertical dipping in and out that names the churn. The tag is additionally silent on which orifice is penetrated and on the support surface, and it subsumes the catalog's own static piledriver entry, in which the penetrating partner may stand rather than squat and enters downward without the churning motion.
Doggy over 69 + 69, doggystyle, all_fours, cunnilingus, on_back, on_bed	group_sex	broader	4	group_sex records only that three or more participants are involved and discards the entire stack that defines this entry - a supine partner beneath a second crouched in head-to-toe 69 alignment, with a third entering that crouched partner from behind.
Three-Woman Tribbing Chain + interlocked_legs, leg_between_thighs, on_back, spread_legs, lying, on_bed	tribadism	broader	4	tribadism names the act alone, vulva-to-vulva contact and motion between partners, and its wiki names the scissored position as its most recognized form; it is the tag the catalog's scissoring entry already carries. It discards the third partner and the chain itself: three partners crossed at the hip in sequence, the middle one engaged on both sides, run end to end rather than closed into a ring.
Gangbang (kneeling center) + kneeling, fellatio, standing	group_sex	broader	4	group_sex records only that more than two participants share a sex act at the same time, so it covers orgies of multiple distinct couples, love trains, foursomes and any threesome of any shape. It discards every feature that individuates this entry: the many-onto-one polarity in which one receiver serves several partners rather than couples pairing off, the hub geometry in which the kneeling central figure is the fixed point while the partners stand in a surround, and the sequential oral service. Routing disclosure: the gangbang tag was rejected because its own page sets the floor at four or more people while this entry has three, but danbooru is internally inconsistent here, since its threesome page states the floor as three or more. The tag was rejected on the stricter of the two readings. The threesome tag is absent from the permitted vocabulary, so the cardinality distinction cannot be carried at all and is lost at group_sex.
Alternating Partners + cowgirl_position, straddling, on_back, seiza, on_bed	group_sex	broader	4	group_sex records only that more than two participants share a sex act at the same time, and it is the tag the catalog's gangbang-center, reverse-gangbang and doggy-over-69 entries already carry. It discards the rotation that defines this entry, two partners taking turns with one receiving partner on a rhythm while the waiting one stays in contact by hand or mouth, along with the MFM composition. At any instant the live half is an ordinary two-person position, by default a ride on the supine partner, and no live tag was found for the swap itself.
Reverse gangbang + girl_on_top, sitting_on_face, on_back, on_bed	group_sex	broader	4	group_sex records only that three or more participants are engaged and carries none of the defining polarity: a single largely static supine partner outnumbered by three or more who direct all attention inward, which is the entire point of the composition.
Reverse Spit Roast + seiza, standing, sandwiched, turning_head, on_bed	group_sex	broader	4	group_sex records only that more than two participants share a sex act at the same time, so it covers threesomes, gangbangs and orgies of any shape, and it is the tag the catalog's gangbang-center, reverse-gangbang and doggy-over-69 entries carry. It discards everything that individuates this entry: one kneeling partner flanked by two standing partners, oral service running from the middle outward, the turn from one partner to the other that drives the scene, and the exact count of three.
Scissoring (tribadism) + lying, on_back, spread_legs, on_bed	tribadism	broader	4	tribadism covers all vulva-to-vulva grinding, including the stacked form with one partner lying on top of the other; it throws away the defining scissored leg interlock with the two heads at opposite ends.
Seated Scissoring + sitting, leaning_back, arm_support, face-to-face, interlocked_legs, on_bed	tribadism	broader	4	tribadism is a pure act tag for female-to-female genital contact and motion, and it is the tag the catalog's supine scissoring entry already owns, so it covers lying, stacked and seated forms alike. It discards the seated arrangement that defines this entry: both partners sitting up and leaning back onto their hands with the legs scissored, so that the hips stay in contact and both faces share one frame; sitting, leaning_back, arm_support and interlocked_legs restore that only as separate postures.
Stand and Deliver + hands_on_own_knees, bent_over, standing, sex_from_behind	standing_doggystyle	broader	4	standing_doggystyle fixes standing rear entry with the receiver bent over, and its wiki names the usual cases as bent over furniture, braced against a wall, or with an arm held back. It discards the self-bracing that defines this entry, the receiver's hands on their own knees or thighs with nothing in the room carrying any load, and it is the tag the catalog's standing-doggy entry already owns exactly. hands_on_own_knees in support carries the bracing.
Standing Line-Up + side-by-side, bent_over, standing, behind_another	standing_doggystyle	broader	4	standing_doggystyle fixes one receiving partner standing and bent over while penetrated from behind, and it is the tag the catalog's standing-doggy entry owns, so it reads as a one-on-one pairing. It discards the second receiving partner bent over alongside the first at matched height and the single penetrating partner moving between them, which is the entire formation this record names.
The Anchor + standing, bent_over, arm_support, sex_from_behind	standing_doggystyle	broader	4	standing_doggystyle fixes only that the receiver stands bent over and is entered from behind, and its wiki lists bending over furniture, bracing against a wall or an arm held back as the usual forms, so it covers the catalog's standing-doggy, bent-over-furniture, stand-and-deliver and the-ladder entries alike. It discards the low fixed brace that names this entry: both hands taking the receiver's weight on a chair back or a bed frame below shoulder height, holding the torso at a shallow angle rather than folded, which only arm_support partly restores. The floor brace the entry also lists sits outside the tag's bent-over wording, since the bent_over wiki routes hands and feet on the ground to bear_position.
The Ladder + standing, bent_over, arm_support, sex_from_behind, on_stairs, stairs	standing_doggystyle	broader	4	standing_doggystyle fixes only that the receiver stands bent over and is entered from behind, on any footing, so it covers the catalog's standing-doggy, the-anchor and bent-over-furniture entries alike. It discards the staircase that defines this entry: the receiver's hands two or three risers up and the penetrating partner a step lower, the stepped geometry that stands in for a height difference, which on_stairs and stairs restore only as a location.
Face-to-Face Tribbing + lying_on_person, on_back, face-to-face, belly-to-belly, breast_press, on_bed	tribadism	broader	4	tribadism names the act alone, vulva-to-vulva contact and motion between two women, and its wiki names the scissored form as the most recognized position; the catalog's scissoring entry already carries it. It discards what separates this entry from scissoring: the stacked, aligned arrangement, one partner supine and the other lying full length on top chest to chest with both long axes pointing the same way, which trades sight of the contact for full-body and eye contact.
Tribbing with Oral + interlocked_legs, on_back, spread_legs, on_stomach, on_bed	tribadism	broader	4	tribadism names only the act, female-to-female genital contact with the partners' vulvas moving against each other, and it is the tag the catalog's scissoring entry already carries; its wiki mentions the scissored legs only as the most recognized position, not as a requirement. It discards the third partner entirely, and with it the oral contact delivered from the open side of the crossed legs, which is the only thing that separates this entry from plain scissoring. on_stomach in the support set places a prone third body, but nothing in the crosswalk records which partner it is working on.
Cicada Clings + on_stomach, lying_on_person, legs_together, sex_from_behind, on_bed	prone_bone	broader	3	prone_bone constrains only the receiving body, flat on the stomach and entered from behind, and is the tag the catalog's own prone-bone entry already uses. It discards the legs held together, the upper partner lying full length along the back, and the clinging stillness the record emphasizes. legs_together and lying_on_person restore the first two; the stillness is a matter of motion, which no still-image tag carries.
Elephant Posture + on_stomach, lying_on_person, sex_from_behind, on_bed	prone_bone	broader	3	prone_bone constrains only the receiving body, flat on the stomach and penetrated from behind, and says nothing about the penetrating partner. It discards the low, heavy line that names this entry, the partner stretched full length along the receiver's back with the two bodies pressed together, and it is the same tag the catalog's prone-bone, jockey and cicada-clings entries carry, so the four cannot be told apart through it.
Fellatio, head back (edge of bed) + irrumatio, deepthroat, lying_upside-down, on_back, standing, on_bed	fellatio	broader	3	fellatio names only the oral act and discards the entire geometry that defines this entry - the receiver supine with the head dropped back over a bed or table edge so that mouth and throat align on one axis with a partner standing at their head - covering equally kneeling, seated, side-lying and POV oral.
Fellatio (kneeling) + kneeling, standing	fellatio	broader	3	The tag names only the oral act and discards the entire structural definition of this entry - the giver kneeling and the receiver standing or seated so the height difference aligns mouth to hip - covering equally lying, reclined, seated, POV and from-behind fellatio.
Fellatio (recipient reclined) + sitting, on_stomach, spread_legs, chair	fellatio	broader	3	fellatio names the act alone and discards all staging: the reclined seated recipient and the giver lying or crouched between their legs with the head at lap height. The catalog's fellatio-kneeling, fellatio-seated, fellatio-head-back and double-blowjob entries all carry the identical tag.
Fellatio (seated recipient) + kneeling, on_chair, sitting, spread_legs	fellatio	broader	3	fellatio names the act alone and discards the staging: it does not record that the recipient sits on seated furniture while the giver kneels between their knees, so it equally covers standing, lying, and from-behind arrangements.
Jockey + on_stomach, straddling, sitting_on_person, sex_from_behind, vaginal, on_bed	prone_bone	broader	3	prone_bone fixes only that the receiver lies flat on the stomach and is penetrated from behind; its wiki says nothing whatever about the penetrating partner. What is discarded is the high upright seat of the rider, which is the entire distinction of the jockey from a top lying down along the receiver's back, and the receiver's legs-together closure, for which the permitted vocabulary has no tag at all (no legs_together, closed_legs, knees_together or feet_together entry, verified by grep). The support set recovers only that the top sits astride the partner, via sitting_on_person plus straddling; no tag in the permitted vocabulary separates an upright seated top from one prone along the receiver's back.
Prone bone + on_stomach, sex_from_behind, lying_on_person, on_bed, vaginal	prone_bone	broader	3	prone_bone constrains only the receiving body, flat on the stomach, penetrated from behind, and says nothing about the penetrating partner, so it discards the plank-above contact that defines this entry: the top partner lowered full-length onto the receiver with weight settling through the receiving pelvis. The tag equally covers the jockey arrangement, where the top partner sits astride the receiver's thighs with no body-length contact, and it does not record whether the receiver's hips stay against the surface or are lifted.
Four-Person 69 + lying, on_back, side-by-side, shared_bed, on_bed	69	broader	3	69 names one mutually inverted pair giving oral to each other at once, and it is the tag the catalog's sixty-nine and sideways-69 entries already carry, so it holds each half of this arrangement but not the whole. It discards the second pair working alongside on the same surface, which is the only thing that makes this a four-person entry, and because nobody crosses between pairs no ring tag such as daisy_chain_(sex) applies either. side-by-side and shared_bed in the support set restore only that the pairs lie next to each other on one bed.
Sideways 69 + on_side, lying, cunnilingus, fellatio, on_bed	69	broader	3	69 covers every mutual-oral arrangement, one partner stacked on top of the other, kneeling, and the upright variant the permitted vocabulary tags separately, and discards the side-lying lateral arrangement in which neither body carries the other's weight, which is what makes this the sustainable member of the family.
Sixty-nine (69) + lying, on_back, on_bed, fellatio, cunnilingus	69	broader	3	The tag covers mutual oral in every orientation: side-lying (catalog sideways-69), the upright carried form (which the permitted vocabulary holds under the separate tag upright_69, itself undocumented), and the doggy-over-69 stack. It does not encode this entry stacked prone-over-supine geometry on a flat surface, nor which partner is underneath.
Stacked Oral + on_back, lying_on_person, human_stacking, sandwiched, on_bed	69	broader	3	69 fixes two people mutually inverted with their genitals at each other's faces, so it covers the catalog's sixty-nine and sideways-69 entries and, here, only the lower pair of the stack. It discards the third partner layered above in the alternating head-to-toe orientation, and with it the three-tier chain that makes this a sixty-nine extended by one layer, with oral contact running through all three partners.
Kneeling embrace + hug, mutual_hug, sex, vaginal, on_bed	kneeling	broader	2	kneeling is a bare posture tag covering solo and non-sexual kneeling; it does not encode that both partners kneel upright, that they face each other chest-to-chest in a full-length embrace, or that penetration is occurring, and it says nothing about the grinding rather than thrusting motion.
Four-Person Daisy Chain + on_side, lying, head_between_thighs, on_bed	daisy_chain_(sex)	broader	2	daisy_chain_(sex) is the tag the catalog's daisy-chain entry carries as exact, and its wiki admits any ring of three or more people each giving and receiving oral at once, so it does not fix the four or more bodies this entry says are needed to close the loop. It also says nothing of the layout, a square with right-angle turns or a rough circle with each body rotated about ninety degrees from its neighbor, so the count and the geometry are lost while the act and the closed ring survive.
Solo display (kneeling) + nude, nude_modeling, looking_at_viewer, on_bed	kneeling	broader	2	kneeling covers every kneeling posture in any context, including kneeling during partnered sex and kneeling fully clothed. It records neither the tall upright torso held over vertical thighs, the wiki fixes only that the knees are down and the buttocks are off the heels, which admits any torso angle from upright to folded forward, and the permitted vocabulary holds no upright-kneel tag, nor the pin-up display intent, nor the single-figure framing, since the permitted vocabulary contains no solo or participant-count tag (verified absent).
Spooning + on_side, sex_from_behind, vaginal, on_bed, hug_from_behind	spooning	broader	2	The tag defines a nested side-lying arrangement and adds only that it also refers to the sex position, so it covers fully clothed non-sexual cuddling and sleeping on the same footing. It therefore discards the fact that rear-entry vaginal penetration is occurring at all.
The Scoop + on_side, curled_up, sex_from_behind, on_bed	spooning	broader	2	spooning defines two partners lying on their sides front to back, and its wiki applies it to cuddling as readily as to the sex position. It discards the receiver's forward curl into a tight C with the penetrating partner nested into that curve, the feature that opens the angle from behind and separates this entry from the catalog's own spooning entry, which owns the same tag.
Teaspoon + on_side, sex_from_behind, leg_lift, on_bed	spooning	broader	2	spooning fixes a nested side-lying pair with one front against the other's back and adds only that it also refers to the sex position, and its wiki gives cuddling as an example, so it holds equally for clothed, non-sexual pairs. It discards the receiver's upper leg lifted high and held well past horizontal, the single feature separating this entry from the catalog's spooning entry, whose own description lists raising the top leg as a variation. leg_lift in the support set carries the raised leg, and sex_from_behind carries the rear entry that the primary tag does not assert.
The Tree + interlocked_legs, hug, face-to-face, on_bed	kneeling	broader	2	kneeling is a bare posture tag, knees on the ground and butt off it, that applies to solo, clothed and non-sexual kneeling at any torso angle, so it records neither the second partner nor that penetration is occurring. It discards the two upright torsos facing each other with heads level, the interlocked thighs with one partner's knees inside the other's, and the small hip movement that drives the position, and it is the same tag the catalog's kneeling-embrace entry carries. interlocked_legs, hug and face-to-face in the support set restore the leg weave, the embrace and the facing, but no live tag fixes an upright kneel as opposed to a forward lean.
Anilingus (from behind) + all_fours, kneeling, on_bed, sex_from_behind	anilingus	broader	1	anilingus names the act alone. It drops the arrangement that this record is about, receiver on all fours with hips raised setting the working height, giver kneeling behind and bowing into it, and the permitted vocabulary's standing_anilingus sibling proves the tag spans other arrangements.
Anilingus (receiving prone) + on_stomach, lying, behind_another, on_bed	anilingus	broader	1	anilingus names the act alone, oral contact at the anus, at any arrangement; it is the tag the catalog's anilingus-kneeling entry already carries, and its narrower standing_anilingus tag shows it spans standing receivers too. It discards the arrangement this entry is about: both partners lying prone and offset lengthwise, the receiver flat with the hips level or slightly propped and the giver lying behind and below with the head at the hips, so neither partner holds a position.
Ballet dancer (leg on shoulder, standing) + standing_on_one_leg, standing_split, holding_another's_leg, vaginal	standing_sex	broader	1	standing_sex records only that the receiving partner is upright on their feet. Its wiki spans face-to-face and rear-entry, wall-braced and free-standing, one foot or two, and it discards the single leg raised to the penetrating partner's shoulder in a near-standing-split, which is the entire content of this entry.
Belly to Belly + belly-to-belly, hug, standing, face-to-face	standing_missionary	broader	1	standing_missionary fixes only that both partners stand on both feet facing each other; it is silent on any brace, so the wall-supported standing pair the catalog files as supported-congress takes the same tag. It discards the full frontal press, chest to chest with the pelvises aligned, that names this entry, and the absence of any support but each other. Containment is imperfect the other way as well: the record's variation with one knee lifted to the hip falls outside the tag, whose wiki requires both feet down.
Bridge (arched receiver) + kneeling, spread_legs, on_bed, vaginal	arched_back	broader	1	arched_back is a bare posture descriptor for any backward bend, sitting in Tag Group:Posture, so it equally covers clothed, solo, gymnastic and wholly non-sexual images and says nothing about a partner. It discards the bridge structure itself, meaning the pelvis raised as the high point of the body with shoulders and feet planted rather than a mere lean back, and it discards the entire pairing: the second partner kneeling between the receiver's legs at the raised pelvis, and the vaginal penetration. Only `kneeling` and `vaginal` in the support set recover any part of the pairing, and neither locates the kneeling partner at the raised pelvis.
Bucking Bronco + girl_on_top, straddling, leaning_forward, hands_on_another's_legs, on_back, on_bed	reverse_cowgirl_position	broader	1	reverse_cowgirl_position fixes only that the receiving partner straddles a lying partner while facing away, and it is the tag the catalog's reverse-cowgirl entry owns, so it covers the upright and leaning-back rides as readily as this one. It discards the extreme forward hinge with the hands gripping the partner's shins or ankles, which is the whole identity of this entry and steepens the angle past anything an upright ride produces; leaning_forward restores only a slight lean by its own wiki, and hands_on_another's_legs restores the grip. Containment is also imperfect, because the wiki routes the squatting drive that this entry lists as a variation to reverse_squatting_cowgirl_position.
Double anal penetration + group_sex, girl_on_top, sex_from_behind, on_back, on_bed	double_anal	broader	1	double_anal names only the act, two penises or penis-like objects in one anus. It carries none of this entry's three-body arrangement: the receiver riding one supine partner while the second enters from behind, the MMF composition, or the concentration of all contact on one orifice that separates it from a spit-roast or a two-orifice stack. The tag also admits solo and object cases with no second partner at all.
Double blowjob + kneeling, group_sex, teamwork_(sexual), licking_penis	cooperative_fellatio	broader	1	cooperative_fellatio covers any number of givers sharing one penis in any arrangement, including three or more givers and seated or lying receivers; it does not fix the two side-by-side kneeling givers or the standing receiver that define this entry.
Double Lap Ride + straddling, sitting, side-by-side, couch, on_couch	sitting_on_lap	broader	1	sitting_on_lap records only that one person sits in another's lap and is not a sex tag, so it covers clothed and non-sexual lap sitting and says nothing of the vaginal union. Its own examples run front-to-back, face-to-face and sideways, which matches every facing this entry lets the riders take, including the sideways seat of riders turned toward each other that neither the catalog's face-off nor its seated-rear-entry has. It holds only one pair, so it discards the second lap ride alongside on the same couch, which is what makes this a four-person entry.
Driving the Peg Home + against_wall, standing_leg_lock, standing, grabbing_another's_thighs, belly-to-belly	suspended_congress	broader	1	suspended_congress fixes only that the receiver is lifted and carried in midair facing the partner and says nothing about a wall, so free-standing carries take it on the same footing; it is the tag the catalog's own suspended-congress entry owns, where a wall brace is only a variation. It discards the wall as the load-bearing plane, which this record makes its defining feature: the receiver pinned flat between the partner's body and the wall, with the wall rather than the arms carrying most of the weight. against_wall restores the wall but cannot say that it carries the load.
Drunken Boat + face-to-face, leaning_back, arm_support, interlocked_legs, on_bed	sitting	broader	1	sitting records only that the butt rests on a surface and is not a sex tag at all, and it is already the tag of the catalog's spider entry, the same mutual recline. It discards every identifying feature of this entry: the partners facing each other with the legs interlocked, both leaning back onto their hands at matched angles, the shared rocking of the joined hips that neither partner leads, and the penetration itself; face-to-face, leaning_back, arm_support and interlocked_legs restore only the posture.
Kneeling Wheelbarrow + kneeling, sex_from_behind, grabbing_another's_thighs, arm_support, on_bed	wheelbarrow_pose	broader	1	wheelbarrow_pose fixes only the two-body geometry, one participant's hands on the ground while the other holds their legs up like handles, and roots the tag in the non-sexual wheelbarrow race. It asserts neither rear-entry penetration nor the holder's posture, so it covers the catalog's standing wheelbarrow entry and this kneeling form alike and discards the kneeling partner, which lowers the held hips to kneeling height and cuts the strain on the receiver's shoulders. kneeling and sex_from_behind in the support set restore the partner's posture and the entry, and grabbing_another's_thighs restores the grip.
Lap and Kneel + straddling, sitting, kneeling, on_chair, on_floor	sitting_on_lap	broader	1	sitting_on_lap records only that one person sits in another's lap and is not a sex tag, so it covers clothed and non-sexual lap sitting as readily as a lap ride and says nothing of the vaginal union. Its own examples run front-to-back, face-to-face and sideways, so it holds both facings this entry allows the rider, but it discards the third partner kneeling on the floor beside the chair and working the seated partner by mouth or hand, which is what turns the catalog's face-off or seated-rear-entry into this three-person arrangement.
Missionary, legs wrapped + missionary, on_back, vaginal, on_bed, hug	leg_lock	broader	1	leg_lock covers legs wrapped around a partner in any configuration - standing sex, suspended congress, cowgirl, and around the head as well as the waist - and discards the supine face-to-face missionary stack on a flat surface that this entry builds the wrap onto.
Three-Man Double Team + human_stacking, lying_on_person, on_back, sex_from_behind, on_bed	double_anal	broader	1	double_anal names only the act, two penises or penis-like objects in one anus, and it is the tag the catalog's double-anal entry already carries. It discards the all-male cast and the three-layer stack that define this entry: the middle partner lying prone along a supine base partner while the third works from above and behind in a plank. Because its wiki admits penis-like objects, it also holds for toy cases with no second partner at all.
Oral Relay + kneeling, standing, side-by-side, cheek-to-cheek, on_bed	cooperative_fellatio	broader	1	cooperative_fellatio records only that two or more people perform fellatio on the same partner, so it covers simultaneous sharing, larger groups of givers and any staging alike, and it is the tag the catalog's double-blowjob entry already carries. It discards the relay that defines this entry: the two kneeling partners trading the contact back and forth on a rhythm, one working by mouth while the other works by hand, so neither waits idle. No live tag names turn-taking, so the swap cannot be recovered from the crosswalk, and cheek-to-cheek in the support set carries only the shared staging of the two heads.
The Sidewinder + on_back, on_side, kneeling, on_bed	twisted_torso	broader	1	twisted_torso is a bare posture tag for a torso turned to a high degree, which its wiki says artists use to show the front and the back of one figure at once, and it carries no partner, surface or penetration. It discards the direction of the twist that defines this entry, the shoulders flat to the surface while the hips roll onto one side, and the penetrating partner kneeling into that twist. on_back and on_side are emitted together in support to carry the shoulder and hip orientations separately.
Solo display (arched) + on_back, lying, looking_at_viewer, nude, on_bed	arched_back	broader	1	arched_back names only the spinal curve as a body attribute; it does not record that the figure is alone, supine, and presenting deliberately to camera, so it equally covers arched backs in standing, kneeling and partnered penetrative scenes.
Spider (crab) + sex, vaginal, spread_legs, on_bed	sitting	broader	1	sitting records only that the butt rests on a surface and is not a sex tag at all. It discards every identifying feature of this entry: the mutual backward recline onto both partners' hands, the legs interleaved past each other's torsos, the hips pressed together into the X silhouette, the face-to-face orientation, the rocking rather than thrusting drive, and the vaginal penetration itself.
Standing Carry, Rear Entry + standing, front-to-back, hands_on_another's_thighs, sex_from_behind	reverse_suspended_congress	broader	1	reverse_suspended_congress records only that a partner is held in midair and entered from behind, and its wiki adds that a full nelson, with the receiver held by the back of the neck, often goes with it. It is the tag the catalog's ekiben entry holds at exact for the carry with the knees hooked over the carrier's arms, so it covers that hold and the full nelson as readily as this one. It discards the hold that defines this entry: the receiver carried under both thighs with the back against the carrier's chest and no neck grip, which is what forces the carrier's deep counter-lean.
Standing face-to-face (leg raised) + standing_on_one_leg, holding_another's_leg, hug, standing, vaginal	standing_sex	broader	1	standing_sex fixes only that the receiver is upright on one or both feet. It discards the face-to-face orientation (the wiki's own example list runs sex from behind and standing doggystyle alongside standing missionary), the single leg lifted and hooked over the penetrating partner's hip, the fact that the penetrating partner is also standing, and the vaginal act. The orientation is not recoverable from this pool at any strength: there is no face-to-face and no looking_at_another tag in it (both verified absent), and hug only asserts the embrace, not which way the bodies face.
Supported Congress + against_wall, leaning, standing	standing_missionary	broader	1	standing_missionary fixes the face-to-face orientation with both partners standing on both feet and says nothing about support, so it covers free-standing face-to-face sex on the same footing. It discards the wall or post that takes the shared weight, which this entry treats as its defining element. Its both-feet condition also routes the raised-leg variation out of the tag, to standing_sex.
The Chairman + sitting_on_lap, straddling, sitting, on_chair	reverse_upright_straddle	broader	1	reverse_upright_straddle fixes only that the receiving partner sits on the penetrating partner's lap facing away and is entered from behind, and it is the tag the catalog's seated-rear-entry entry owns, so it covers couch and floor seats as readily as a chair. It discards the upright chair that carries the seated partner completely and the receiver's feet planted on the floor either side, which together put all of the movement in the receiver's legs; on_chair and straddling restore those only as separate postures.
The Drill + missionary, crossed_ankles, on_back, face-to-face, on_bed	leg_lock	broader	1	leg_lock fixes only that one partner's legs wrap another's torso; its wiki says the hold is frequently done during missionary sex, and its own examples add an upright straddle and a standing leg lock, so it covers the catalog's missionary-legs-wrapped entry as readily as this one. It discards the ankles crossed behind the penetrating partner's back on a supine face-to-face stack and the clamp that shortens the stroke to almost nothing, the mechanism that defines this entry. The wiki names pulling the partner closer only as a common purpose of the hold, not as a clamp that caps the stroke, and crossed_ankles restores the crossing but not where it sits.
The Twister + on_side, on_back, crossed_legs, kneeling, on_bed	twisted_torso	broader	1	twisted_torso is a bare posture tag for a torso turned to a high degree, which its wiki says artists use to show the front and the back of one figure at once, and it carries no partner, surface or penetration. It discards which way the wring runs, the pelvis on its side while the upper body rotates back toward the ceiling so the twist sits in the lower spine, together with the leg carried across the midline and the partner kneeling into the opening, so the tag cannot tell this entry from its mirror, the catalog's sidewinder. on_side and on_back in the support set carry the pelvis and the shoulders separately, crossed_legs the crossed leg and kneeling the partner.
Wheelbarrow + sex_from_behind, vaginal, standing, grabbing_another's_thighs	wheelbarrow_pose	broader	1	wheelbarrow_pose fixes only the two-body geometry (one participant's hands on the ground, the other holding their legs up like handles) and roots the tag in the non-sexual wheelbarrow race. It asserts neither the rear vaginal penetration nor that the lifting partner is upright at hip height, so it subsumes the SFW race instance alongside this one.
Bent over furniture + sex_from_behind, vaginal, bent_over, leaning_on_table, table	bent_over_furniture	broader	0	bent_over_furniture names only the posture and is routinely used for fully clothed, non-sexual bending over a desk or sofa arm with no second person present, so the rear-entry vaginal penetration and the partner standing behind are both dropped.
Bukkake circle + kneeling, standing, cum_on_body, on_bed	bukkake	broader	0	bukkake names the many-onto-one ejaculation act and nothing about staging: the wiki admits a receiver who is sitting or lying as readily as kneeling, and says nothing about where the ejaculating partners are placed, so it applies equally to a single line of partners or to a receiver on their back. The ring geometry that defines this entry, one kneeling figure encircled by three or more standing partners, is therefore discarded, and the permitted vocabulary cannot recover it, having no tag for a surrounding or encircling arrangement and no participant-count tag. The facial finish that the entry treats as the organising event is only approximated: the delivered pool contains neither facial nor cum_on_face (both verified absent), and danbooru treats facial as a tag distinct from cum_on_body, so cum_on_body stands in for a finish it does not strictly denote.
Bunk Beds + missionary, legs_up, on_back, lying_on_person, on_bed	human_stacking	broader	0	human_stacking records only that several people lie stacked on top of one another, and its wiki says the stack often presents the bodies to the viewer, so it covers display stacks in which no partner is engaged at all. It discards the pairing into two couples, the intercourse inside each tier, and the load path that defines this entry, the upper pair carried on the lower pair's raised knees and hands so that the stack holds two separate levels.
Deep Throat + kneeling, standing, head_back	deepthroat	broader	0	deepthroat names the depth alone, the whole penis taken down the throat, and its wiki extends it to dildos and other objects, so it holds with no partner present and in any staging; the existing facefuck-kneeling and fellatio-head-back rows already carry it as a support tag. It discards the kneeling giver below a standing partner and the extended neck that lines up mouth and throat on one axis, which the record names as the identifying feature.
Double Manual + on_back, lying, seiza, sandwiched, on_bed	cooperative_handjob	broader	0	cooperative_handjob fixes only the act, two or more people performing a handjob on the same penis, and says nothing about staging, so it equally covers standing, seated and three-giver arrangements. It discards the receiving partner lying or reclining between two partners kneeling on either side, and it assumes a penis as the target, which this record's FFM composition suggests but does not state.
Double vaginal penetration + girl_on_top, sex_from_behind, group_sex, straddling, on_bed	double_vaginal	broader	0	double_vaginal is a pure act tag, two penetrating members sharing one vaginal entry, with no arrangement content at all. It discards the stack this entry specifies: the receiver riding a supine partner while the second partner aligns from behind into the same entry, and with it the convergence constraint that restricts both partners to small negotiated movement. Side-by-side, both-from-front, standing and lying stacks all take the identical tag.
Facefuck (kneeling, irrumatio) + kneeling, head_grab, deepthroat	irrumatio	broader	0	irrumatio encodes the active/passive inversion but no staging: it is used equally for supine and head-hanging-off-the-bed versions (catalog fellatio-head-back), so the kneeling receiver with the thrusting partner standing over them is not recorded.
Fingering (partner lying) + on_back, spread_legs, kneeling, lying, on_bed	fingering	broader	0	fingering marks manual penetration with no posture attached: it covers standing, from-behind, and through-clothing versions, and does not encode the supine receiver with knees raised and parted or the partner kneeling alongside.
Footjob (seated facing) + two-footed_footjob, sitting, on_chair	footjob	broader	0	footjob names the act alone and discards the staging: it does not record the giver's reclined seated posture facing the recipient on seated furniture, so it equally covers standing, from-behind and under-table arrangements that the permitted vocabulary names separately.
Frottage (face-to-face grinding) + lying_on_person, on_back, pelvic_thrust	frottage	broader	0	frottage records only that genitals are rubbed against another person's body, in any arrangement and against any body part, so it discards this entry's fixed staging: the face-to-face missionary stack on a flat surface with one partner above. It also under-covers rather than merely over-covers. The wiki routes direct genital-to-genital contact away to pussyjob, buttjob, tribadism, bulges touching or penises touching, and the clothed form away to dry humping. For this MF face-to-face grind the applicable successors are pussyjob for the nude reading and dry_humping for the clothed one, and verification confirmed both are absent in the permitted vocabulary although both exist on danbooru (5629 and 1206 posts), as are bulges_touching and penises_touching. buttjob and tribadism ARE in the permitted vocabulary, but neither can carry this case on its own wiki: buttjob is 'a person grinds their ass against their partner's penis' with the penis facing the partner's upper body, a rear geometry, and tribadism is 'female-to-female genital sex' between vulvas, while this row is MF and face-to-face. frottage is therefore kept as the best available tag, reliably true of this entry only on the body-contact reading; on the direct genital-to-genital reading, clothed or nude, the wiki hands the case to an out-of-pool tag and nothing in the crosswalk carries it.
Full nelson + folded, legs_up, wide_spread_legs, sex_from_behind, vaginal	full_nelson	broader	0	full_nelson denotes an arm lock, not a sex position. Its wiki defines a wrestling hold, so the tag covers clothed non-sexual wrestling art in which no penetration occurs at all, and where it is sexual the wiki's stated default pairing is reverse suspended congress, in which the receiver is held in midair. The tag therefore fixes neither that penetration is happening nor that the penetrating partner is lying or seated behind, leaving the carry versus lying versus seated axis that the catalog record pins wide open.
Gangbang Line + all_fours, doggystyle, queue, kneeling, standing, on_bed	gangbang	broader	0	gangbang fixes only the polarity and the count, three or more people having sex with a single person, and says nothing of staging or sequence, so it covers ring and hub stagings and scenes with several contacts live at once as readily as a line. It discards the queue that defines this entry, the waiting partners lined up single file behind the receiver and cycling through one rear slot so that only one contact is live at a time, along with the receiver's all-fours base; queue, all_fours and doggystyle in the support set restore these only as separate facts.
Handjob (partner lying) + kneeling, on_back, lying, on_bed	handjob	broader	0	handjob names the manual act only and discards the arrangement that defines this entry - the recipient fully extended supine while the partner kneels alongside the hips - covering equally standing, seated, POV, cuddled and from-behind manual stimulation.
Intercrural (standing) + standing, frottage, sex_from_behind	thigh_sex	broader	0	thigh_sex names the non-penetrative act only and is used equally for lying and face-to-face variants; it discards that both partners are standing and that the thrusting comes from behind between thighs held closed and nearly straight.
Intergluteal (hotdogging) + on_stomach, on_bed, grabbing_another's_ass	buttjob	broader	0	buttjob fixes only the act, genital-to-gluteal grinding with no penetration, and discards the arrangement this entry commits to: the receiver lying prone on a flat surface with the penetrating partner aligned above from behind. The tag covers standing, seated and reclined grinds equally, and it is agnostic about which partner supplies the motion (its wiki phrases the act as the receiver grinding their ass against the partner, while this entry has the partner thrusting along a passive prone cleft).
Three-Man Spit Roast + all_fours, kneeling, standing, sex_from_behind, on_bed	male_spitroast	broader	0	male_spitroast fixes only that the partner in the middle is male, performing oral at the front while penetrated anally from behind. Its wiki admits partners who do not present as male, such as one using a strap-on, among those penetrating him, and it leaves the partner at the front unspecified, so it does not fix the all-male cast that is this entry's only difference from the catalog's spit-roast. Like its parent spitroast, it also leaves the middle partner's posture open (the parent's wiki lists standing, seiza and all fours among others) and so discards the hands-and-knees default.
Mutual masturbation (side by side) + female_masturbation, male_masturbation, lying, on_bed	masturbating_together	broader	0	masturbating_together records only that two characters masturbate in the same place. It discards the side-by-side arrangement lying on one shared bed, the mutual watching by which arousal is exchanged, and the equal two-shot framing that composes the entry.
Paired Side by Side + side-by-side, shared_bed, missionary, on_back, on_side, on_bed	orgy	broader	0	orgy records multiple couples or distinct groups having sex alongside one another, which is this entry's structure, but it admits any number of couples and groups of any size in any position, so it does not fix the two pairs, the four bodies or the single shared surface. This entry leaves each pair's position open, so the support set pins only the record's default staging of one missionary pair beside a side-lying pair, and no arrangement tag restores the count.
Rusty trombone + reach-around, handjob, kneeling, female_rimming_male, bent_over	standing_anilingus	broader	0	standing_anilingus covers ordinary rimming of a standing partner; it drops the simultaneous manual reach-around to the front, which is the sole feature separating the rusty trombone from plain standing anilingus.
Sidesaddle cowgirl + sitting_on_person, on_back, vaginal, on_bed	girl_on_top	broader	0	girl_on_top records only that a girl is above another character, and its wiki does not even require the situation to be sexual, so it discards the sidesaddle geometry entirely: both of the rider's legs swung to one side instead of straddling, and the full profile line to camera that follows from it. the permitted vocabulary has no tag for legs-to-one-side over a person (re-verified by grep). The nearest wiki routing is a dead end that must be disclosed rather than followed: sitting_sideways sends the sideways-riding sense to the tag sidesaddle, which is absent in the permitted vocabulary though it exists on danbooru at 2262 posts, and whose wiki scopes it to 'Riding something with both legs on the same side. Applies to saddled animals such as horses as well as brooms', not to a supine partner. The defining geometry is therefore an explicit reconstruction gap.
Solo all-fours (look back) + looking_back, looking_at_viewer, ass_focus, from_behind, on_bed	all_fours	broader	0	all_fours names only the hands-and-knees posture; it drops the head turned back over the shoulder to the lens, which is the single feature separating this pose from a plain all-fours hold, and it is applied just as often to partnered sex images so it carries no solo condition.
Legs raised (supine) + lying, on_back, on_bed, looking_at_viewer	legs_up	broader	0	legs_up records only that the legs are raised. It does not encode the supine torso, the legs held straight and together rather than parted (the permitted vocabulary's spread_legs marks the opposite, catalog solo-spread-legs), or the single-participant display framing, and it is applied equally to raised legs during partnered sex such as mating press.
Masturbation (seated) + sitting, on_chair, chair, spread_legs	male_masturbation	broader	0	The tag fixes only actor and act, 'Masturbation of a male', and covers standing, lying, kneeling and prone male solo equally. It discards the seated framing that defines this entry: the performer reclined back into the support of a chair or couch with the upper body resting into it and one hand working at the lap.
Masturbation (supine) + on_back, lying, spread_legs, fingering, legs_up, on_bed	female_masturbation	broader	0	female_masturbation names the act at any posture - standing, seated, bent over, in water - and discards the supine, knees-drawn-up arrangement on a flat surface that this entry specifies.
Face down, hips up (solo) + ass_focus, arched_back, looking_back, on_bed, nude	top-down_bottom-up	broader	0	The tag encodes only the posture of chest lowered and hips raised; it does not encode that the figure is alone and presenting to camera, so it equally covers partnered rear-entry scenes built on the same posture, such as leapfrog.
Legs spread (supine) + on_back, lying, wide_spread_legs, looking_at_viewer, on_bed	spread_legs	broader	0	The tag records only that the legs are apart, in any body orientation - standing, seated, kneeling, on the back - and discards the supine posture with knees drawn up and feet planted plus the straight-on frontal presentation to the lens that organises this pose.
Solo display (squat) + spread_legs, wide_spread_legs, looking_at_viewer, completely_nude, nude_modeling	squatting	broader	0	squatting records only the deep knee fold and covers clothed, casual and multi-person crouches; it discards the knees-driven-wide upright-torso frontal display to camera and the furniture-free, balance-dependent hold.
Solo display (standing) + looking_at_viewer, nude_modeling, completely_nude	standing	broader	0	standing records only that the figure is upright; it drops the weight-shifted hip counter, the full-length presentation to camera, and the single-model framing, and applies equally to clothed figures standing inside any multi-person scene.
Toy riding (solo) + squatting, female_masturbation, vaginal_object_insertion, looking_at_viewer, on_bed	dildo_riding	broader	0	dildo_riding encodes the act and the toy's fixture and nothing else. It does not encode the single-participant framing, the wiki constrains the toy, not the cast, so the tag holds equally in scenes where a partner is present, and the permitted vocabulary contains no solo tag (verified absent), so participant count cannot be asserted at all. It does not fix which orifice is used, which is why vaginal_object_insertion is carried separately. And it does not distinguish the two rides the entry admits; support pins the deep squat, leaving the kneeling ride unencoded, since asserting both would be self-contradictory.
Spread Eagle + missionary, on_back, spread_arms, spread_legs, face-to-face, on_bed	spread_eagle_position	broader	0	spread_eagle_position is a posture tag, listed in Tag group:Posture, and its wiki fixes only that a person lies with arms and legs outstretched and spread apart, so it covers solo, clothed and non-sexual sprawls as readily as this entry. It discards the entire pairing, the penetrating partner working above the receiver face to face, which only the missionary and face-to-face support tags restore.
The Peg + on_side, kneeling, straddling, holding_another's_leg, on_bed	leg_lift	broader	0	leg_lift is a bare posture tag for one leg lifted up and away from the other, which rests, and it fixes no body orientation, partner or penetration, so it covers solo, clothed, standing and lying poses alike. It keeps the raised upper leg spread wide from the resting lower leg, but not the near-vertical angle that makes the peg this entry is named for, and it discards the side-lying receiver, the penetrating partner kneeling astride the lower thigh, and the partner holding the raised leg upright, which only the support tags carry.
The Wraparound + sitting_on_table, sitting, standing, face-to-face	standing_leg_lock	broader	0	standing_leg_lock fixes only that the legs are wrapped around a partner who is standing, and its wiki lists a hug carry among its examples, so it covers carried forms with the receiver lifted clear of the ground, such as the catalog's suspended-congress, as readily as this one. It discards the feature that defines this entry, the receiver seated upright on the edge of a table or counter that carries all the weight, which is the difference between this position and a carry.
The X + interlocked_legs, leg_between_thighs, spread_legs, lying, on_bed	on_back	broader	0	on_back is a bare posture tag, lying on one's own back, that carries no partner and no sex act, so it holds for any supine figure in any context. It discards the whole X: two supine partners with heads at opposite corners, legs scissored at the hips, and neither body supporting the other. The scissor tag cannot stand in, because scissoring is an active alias of tribadism, whose wiki limits it to female-to-female genital sex while this entry is MF, so only interlocked_legs and leg_between_thighs in the support set carry the leg weave.
Thigh Riding + straddling, sitting, on_chair, face-to-face, leg_between_thighs	thigh_straddling	broader	0	thigh_straddling names the arrangement this entry turns on, one partner straddling a single thigh of the other, but its wiki calls it often, not always, a form of frottage, so it holds equally for plain sitting astride a thigh, and it does not fix the straddled partner's posture. It discards the seated partner on furniture and the grinding against that thigh, which the record reads as build-up that is non-penetrative and usually stays clothed.
Triple penetration (airtight) + group_sex, vaginal, anal, fellatio, girl_on_top, sex_from_behind	triple_penetration	broader	0	The tag counts three simultaneous penetrations without specifying which orifices, so it equally covers triple-vaginal and triple-anal stacks; it discards the airtight distribution of exactly one vaginal, one anal and one oral, and says nothing about the three-partners-on-one-receiver arrangement.
Viennese oyster + missionary, on_back, vaginal, spread_legs, deep_penetration, on_bed	legs_over_head	broader	0	legs_over_head is a bare flexibility posture carrying no partner and no penetration - it is used for solo folds and non-sexual contortion - so it drops the ankles crossing behind the receiver's own head, the self-lock, and the penetrating partner pressing down from above face-to-face.
The Ostrich's Tail + legs_up, kneeling, holding_another's_legs, on_bed	piledriver_(sex)	close	4	piledriver_(sex) carries the inversion, the receiver on the shoulders with the hips lifted vertically, but it fixes a partner who squats and enters from above with the receiver's legs folded back. This entry differs on both counts: the penetrating partner kneels and carries the legs up in the fanned shape the name describes, which is why the record places it between an ordinary raised-hip position and a full piledriver. kneeling and holding_another's_legs in the support set carry that difference.
The Pinball Wizard + against_wall, legs_up, kneeling, on_floor	piledriver_(sex)	close	4	piledriver_(sex) carries the inversion, the receiver on the shoulders with the hips lifted vertically, but its wiki mentions no brace, folds the legs back, and has the partner squatting above. It discards the wall or couch front that braces the receiver's back and carries the hold, which the record names as the one thing separating this entry from a piledriver. It also does not match the kneeling partner, and where the wiki folds the legs back, the record names no fold, only legs spread, held together or hooked over the partner's shoulders.
The Plow + legs_over_head, folded, legs_together, standing, on_bed	piledriver_(sex)	close	4	piledriver_(sex) has this entry's inversion, the receiver on the shoulders with the legs folded back and the hips lifted vertically, but its wiki has the partner squatting over the fold, while this entry has the partner standing or kneeling. It also does not record that the legs are carried all the way past the head and held together, the deepest fold in the catalog, and it is the tag the catalog's own piledriver entry already holds as exact.
Five-Point Star + on_side, lying, head_between_thighs, on_bed	daisy_chain_(sex)	close	2	daisy_chain_(sex) names a closed figure of the same kind, three or more people in a circle with each both performing and receiving at once, and it is the tag the catalog's daisy-chain entry carries as exact. It fixes neither the count, five by default, nor the even angular spacing with consistent handedness that turns the ring into a star, and no support tag carries that geometry. Its wiki also makes every contact oral, while this record is coded for mixed acts with multiple penetration.
Squat Thrust + squatting, straddling, spread_legs, on_back, on_bed	squatting_cowgirl_position	close	1	squatting_cowgirl_position names the same arrangement, the receiver squatting on the feet over a lying partner and facing them, and it is the tag the catalog's squatting-cowgirl entry already owns exactly. What it does not record is this entry's stress on the full vertical rise and fall driven from the feet, so the tag cannot separate this record from squatting-cowgirl.
Reverse Piledriver + piledriver_(sex), sex_from_behind, top-down_bottom-up, legs_up, squatting, on_bed	reverse_piledriver_(sex)undocumented	close	0	The tag's name matches this entry, but it has no wiki page and only two posts, so nothing about which body is reversed or which way the receiver faces can be sourced from it, and no claim is made about what else its extension admits. The reversal that defines this entry, the inverted receiver turned away from the partner so the face is down and the squatting partner enters from behind, is carried not by the tag but by the top-down_bottom-up and sex_from_behind support tags, while the documented parent piledriver_(sex) anchors the shoulder stand, hips lifted vertically and partner squatting above, though its legs-folded-back clause is narrower than this entry's legs spread or held together above. With two posts the tag gives a booru-trained model almost no signal, so the parent and the posture tags in the support set do the practical prompting work.
Standing 69 (inverted carry) + standing, carrying, fellatio, cunnilingus, 69	upright_69undocumented	close	0	The carry is not in the tag. The tag's NAME mentions only that the 69 is upright, and its wiki body is empty, so nothing about a lift can be sourced from the tag at all. The feature that defines this entry, the lower partner held entirely clear of the ground and inverted against the standing partner (support_surface partner_supported, the mutual oral performed as a strength hold), is carried solely by the `carrying` support tag, with the mutual-oral content anchored by the documented canonical parent `69`. No claim is made about what else this tag's extension admits or excludes, because there is no text to read.

Knowledge base & historical sources 120

Structured entity identifiers exist for only a minority of named positions, which is most of the reason the folksonomy column above had to be built at all. Historical names are attested only: a source is recorded where it actually names the position, never inferred from resemblance.

Position	Namespace	Identifier	Relation	What the mapping discards
Ballet dancer (leg on shoulder, standing)	Historical sourceKhajuraho & Konark temple sculpture	`Raised-leg maithuna`	close	Attested source name. The temple panels' dancers'-line unions, one leg carried high.

Cicada Clings	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Cicada Clings`	close	Attested source name. Fourth of the Nine Ways: the receiving partner prone with the body stretched straight and the partner lying behind. The text then calls for deep entry with a slight lift of the hips and a counted set of strokes, so the stillness and grinding this record emphasizes are not in the source.

Crab Embrace	Historical sourceKama Sutra	`Karkata (the crab's position)`	close	Attested source name. Both legs contracted and held against the stomach. Burton fixes only the legs, so the kneeling partner is the catalog's staging.
Cross Position	Knowledge base	Q11634425	broader	The English label matches this entry, but every defining text on the item describes the whole crossed-legs family: the Japanese description and the four linked articles cover any position in which two women, or a man and a woman, cross the legs and join the genitals between each other's legs, the Japanese article names matsuba-kuzushi as the best-known form, and the item's image is a file named Wiki-tribadism.png. The Cantonese article also gives T-square position as another name, so the item covers the arrangements of the catalog's t-square and scissoring entries as well as this one. It discards the right angle between the supine receiving partner with raised legs and the side-lying penetrating partner that defines this record.
Deep Throat	Knowledge base	Q8401	broader	Q8401 is fellatio in general, labeled 'fellatio' and described as 'oral sex by sucking on the penis'. It names the act this entry is a form of, not the full-depth technique or the kneeling, neck-extended staging that defines it; Wikidata holds the technique as its own item, Q9720, a subclass of Q8401. The catalog's fellatio-kneeling, fellatio-seated, fellatio-head-back and fellatio-lying-recipient-seated entries carry the same item.

First of the Nine Ways: the receiving partner face up and raising the pelvis beneath the partner lying over them, with slow strokes counted eight shallow to two deep. The record raises the knees rather than the pelvis and admits other counts, such as an even alternation, where the text fixes eight to two.

Ekiben (facing-away carry)	Knowledge base	Q116687840	exact
Elephant Posture	Historical sourceKama Sutra	`Aibhika (the elephant posture)`	related	Attested source name. Burton names the pressing of an elephant only in a list of animal variants of the congress of a cow, made on hands and feet, and gives it no posture of its own, so the face-down arrangement here is the catalog's reading rather than the text's.
Entwined Cranes	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Cranes Entwine Necks`	close	Attested source name. Ninth of the Nine Ways: the partner seated with the legs stretched out and apart, the receiving partner astride the thighs with the hands around the partner's neck, and the partner's hands at the hips helping the receiving partner sway and lift. The text's seat has the legs spread forward, not the crossed legs this record specifies.
Face-off (chair straddle)	Historical sourceShijūhatte (the Forty-Eight Techniques)	`Taimen-zai (face-to-face seat)`	close	Attested source name. The standard Japanese term for the facing seated union.

Fishes Interlock	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Fishes Interlock`	close	Attested source name. Eighth of the Nine Ways, not the seventh as the seed note says: the partner supine, the receiving partner astride with the thighs forward, a slow shallow entry, and the receiving partner alone moving. The text describes a plain straddle and no leg interlock, so the weave this record treats as defining is not attested.
Fixing of a Nail	Historical sourceKama Sutra	`Fixing of a nail`	close	Attested source name. One leg raised toward the head, the other stretched out.
Half-Pressed Position	Historical sourceKama Sutra	`Ardha-piditaka (the half pressed position)`	close	Attested source name. One leg extended, the other drawn up. Burton gives it as the half form of the pressed position, the other leg contracted and held at the partner's chest, while this entry's description derives it from the pressing position.

Mare's Position	Historical sourceKama Sutra	`Vadavaka (the mare's position)`	close	Attested source name. Named for the internal grip rather than the outward shape. Burton lists it among the ways of lying down, beside the clasping position, and gives a matching grip made from on top its own name, the pair of tongs, so the astride seat here is the catalog's staging.
Mating press	Historical sourceKama Sutra	`Indranika (Indrani's position)`	close	Attested source name. Thighs drawn back to the sides of the body, the goddess Indrani's form.
Mating press	Historical sourceThe Perfumed Garden of Sensual Delight	`El asemeud (the Stopperage)`	close	Attested source name. Knees pressed to the chest under the partner's weight.
Mating press	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Mounting Tortoise`	close	Attested historical name for this position in the named source; the source wording may describe a variant of the general form.
Mating press	Knowledge base	Q124570588	exact
Missionary	Historical sourceKama Sutra	`Samputa (the clasping position)`	close	Attested historical name for this position in the named source; the source wording may describe a variant of the general form.
Missionary	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Dragon Turns`	close	Attested source name. First of the Nine Ways: the classic supine union.
Missionary	Knowledge base	Q219561	exact
Missionary, legs wrapped	Historical sourceDongxuanzi (Master of the Cavern Mystery)	`Silkworm Spinning a Cocoon`	close	Attested source name. Her legs wrap him as the silkworm wraps its thread.
Monkey's Attack	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Monkey's Attack`	close	Attested source name. Third of the Nine Ways: the receiving partner supine with the thighs carried on the partner's shoulders, the knees pressed back past the chest, and the buttocks and back lifted, the partner pressing deep. The text rests the thighs rather than the lower legs on the shoulders and leaves the partner's stance unstated, so the kneeling carry this record renders is the catalog's staging.
The Ostrich's Tail	Historical sourceThe Perfumed Garden of Sensual Delight	`The tail of the ostrich`	close	Attested source name. The receiving partner's legs raised until only the head and shoulders rest on the ground.
Phoenix Soars	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Phoenix Soars`	close	Attested source name. Sixth of the Nine Ways: the receiving partner supine holding the legs up, the partner kneeling between the thighs with both hands on the mat. The text has the partner kneeling, so the squat on the balls of the feet that this record treats as identifying is not attested.
Piledriver	Knowledge base	Q7193878	exact
Pounding on the Spot	Historical sourceThe Perfumed Garden of Sensual Delight	`Pounding on the spot`	close	Attested source name. al-Nafzawi's 15th manner, Dok el arz: the partner seated with the legs stretched out, the receiving partner astride the thighs with the legs crossed behind the partner's back and the arms around the neck, and the partner helping the receiving partner rise and descend. Burton calls the chapter's sixth movement, a firm pressing motion with no withdrawal, particularly well adapted to this manner; the record keeps only that movement and drops the rise and descent the manner itself describes.
Pressing Position	Historical sourceKama Sutra	`Piditaka (the pressing position)`	related	Attested source name. In Burton the pressing position begins in the clasping position, legs stretched straight out over each other, and adds the receiving partner pressing the other with the thighs; contracted legs held at the chest, as this entry describes them, are his separate pressed position. The entry shares the name and the thigh pressure, not the shape.
Pretzel (pretzel dip)	Historical sourceShijūhatte (the Forty-Eight Techniques)	`Matsuba-kuzushi (scattered pine needles)`	close	Attested source name. The Edo 48's interleaved-leg side entry, the pretzel's ancestor.
Prone bone	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Clinging Cicada`	close	Attested source name. The Nine Ways' prone press, named for a cicada flat against bark.
Prone bone	Historical sourceAnanga Ranga	`Vyanta-bandha (prone class)`	close	Attested historical name for this position in the named source; the source wording may describe a variant of the general form.
Prone bone	Knowledge base	Q116280298	exact
Prone cowgirl	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Fish Linking Scales`	close	Attested source name. The Nine Ways' flat, shallow ride, bodies pressed like fish scales.
Reverse cowgirl	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Rabbit Licks Its Fur`	close	Attested source name. The Nine Ways' rider facing the feet, head bowed.
Reverse cowgirl	Historical sourcePompeian erotic frescoes	`Venus pendula aversa`	close	Attested source name. The turned-away variant of Rome's riding motif.
Reverse cowgirl	Knowledge base	Q875006	exact
Rising Position	Historical sourceKama Sutra	`Bhugnaka (the rising position)`	close	Attested source name. Both legs raised straight. Burton's wording raises the thighs straight up and says nothing about the knees or ankles, so the extended knees and closed ankles here are the catalog's reading.
Rusty trombone	Knowledge base	Q2607227	exact
The Sandwich	Knowledge base	Q134998018	broader	Wikidata's sandwich carries only the label "sandwich" and the description "sex position", and its two sitelinked articles make it wider than this record: the Dutch article has one of three partners lying between the other two, allows other gender mixes and, between men, a middle partner who penetrates while being penetrated, and the Estonian article lets the three stand or lie and gives as its best-known form a receiver astride a supine partner with the back turned toward that partner. It therefore covers the catalog's standing-sandwich and dp-reverse builds as well. It discards what defines this record: the receiver face down along the supine base, the third partner above and behind, and the double penetration.
Seated rear entry (lap ride)	Historical sourceShijūhatte (the Forty-Eight Techniques)	`Haimen-zai (rear-facing seat)`	close	Attested source name. The Japanese named counterpart of the facing seat.
Sideways 69	Knowledge base	Q2349	exact

Spider (crab)	Historical sourceThe Perfumed Garden of Sensual Delight	`El modefeda (Frog Fashion)`	close	Attested source name. Heels drawn to the thighs, partner seated facing, al-Nafzawi's frog.
Spit roast	Knowledge base	Q123731283	exact
Splitting the bamboo	Historical sourceKama Sutra	`Venudaritaka (splitting of a bamboo)`	close	Attested source name. The alternating raised leg is Vatsyayana's own image.
Spooning	Historical sourceDongxuanzi (Master of the Cavern Mystery)	`Mandarin Ducks Entwined`	close	Attested source name. The side-lying pair named for the devoted duck couple.
Spooning	Historical sourceMoche erotic ceramics	`The lying-couple vessels`	close	Attested source name. Side-lying pairs under blankets, a signature Moche domestic scene.
Spooning	Knowledge base	Q1343157	exact
Spread Eagle	Knowledge base	Q12654072	close	Beyond its label 'eagle position', the same name in Lithuanian, Serbian and Esperanto, and the description 'sex position', the item has no aliases, no sitelinks and no statement except instance of sex position (Q8394), so the match rests on the shared name alone. It drops the spread qualifier and fixes neither the four limbs stretched wide nor the partner working above that define this entry.
Standing rear entry (bent over)	Historical sourceDongxuanzi (Master of the Cavern Mystery)	`Late-Spring Donkey`	close	Attested source name. She stands bent with hands toward the ground; he covers her from behind.
Standing rear entry (bent over)	Historical sourceGreek symposium pottery	`Kubda (the bent-over)`	close	Attested source name. Comedy's 'three-obol' position, ubiquitous on symposium ware.
Standing rear entry (bent over)	Historical sourceOld Babylonian erotic plaques	`The beer-drinking congress`	close	Attested source name. The plaques' signature motif: standing rear entry while she drinks through a straw.
Standing rear entry (bent over)	Historical sourceTurin Erotic Papyrus	`Bent-over vignettes`	close	Attested source name. Several of the papyrus's twelve scenes turn on the standing, bent-forward entry.
Standing face-to-face (leg raised)	Historical sourceKama Sutra	`Sthita (the steadied congress)`	close	Attested source name. Standing against a wall or pillar.
Standing face-to-face (leg raised)	Historical sourceAnanga Ranga	`Utthita-bandha (standing class)`	close	Attested historical name for this position in the named source; the source wording may describe a variant of the general form.
Standing face-to-face (leg raised)	Historical sourceKhajuraho & Konark temple sculpture	`Standing maithuna`	close	Attested source name. The upright embracing couples that anchor the temple friezes.
Stopperage	Historical sourceThe Perfumed Garden of Sensual Delight	`Stopperage`	close	Attested source name. A cushion placed under the hips to shorten the passage.
Supported Congress	Historical sourceKama Sutra	`Supported congress`	close	Attested source name. Both partners standing, leaning on a wall or pillar. Burton also admits partners propped only on each other's bodies with no wall, which this entry's against-wall surface leaves out.
Suspended congress (standing carry)	Historical sourceKama Sutra	`Avalambitaka (suspended congress)`	close	Attested historical name for this position in the named source; the source wording may describe a variant of the general form.
Suspended congress (standing carry)	Historical sourceThe Perfumed Garden of Sensual Delight	`Driving the Peg Home`	close	Attested source name. She hangs at his neck, braced against a wall, in Burton's rendering.
Suspended congress (standing carry)	Historical sourceKhajuraho & Konark temple sculpture	`Maithuna standing carry`	close	Attested source name. Carved on the temple walls of Khajuraho, the shastra's carry rendered in stone.
Suspended congress (standing carry)	Historical sourceI Modi (The Sixteen Postures)	`The carried posture`	close	Attested source name. Among the sixteen engraved postures of the Renaissance set.
Suspended congress (standing carry)	Knowledge base	Q11597758	exact
The Swing	Historical sourceKama Sutra	`The swing`	related	Attested source name. Grouped with the positions where the receiving partner takes the active role. In Burton the swing is the man lifting the middle of his body while the woman turns hers round, a turning of the hips rather than the front-to-back rocking this entry describes.
T-square	Knowledge base	Q117314347	exact
The Frog	Historical sourceThe Perfumed Garden of Sensual Delight	`The frog position`	close	Attested source name. The receiving partner on the back with heels drawn to the buttocks.
The Seducer	Historical sourceThe Perfumed Garden of Sensual Delight	`The seducer`	close	Attested source name. al-Nafzawi's 29th manner, El moheundi, in which the kneeling partner sits back on the heels, raises and separates the thighs, and carries the legs under the arms or over the shoulders, the hands at the waist or shoulders. The hands-at-the-knees hold this record treats as defining is not in Burton's text.
Tiger's Tread	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Tiger's Tread`	close	Attested source name. Second of the Nine Ways: the receiving partner bowed face down with the hips raised and the head low, the partner kneeling behind with the arms around the receiving partner's belly and entering deep for a count of five eights. The record sets the receiving partner on the elbows, a support the text does not name, and leaves the hold at the belly and the count open.
Triple penetration (airtight)	Knowledge base	Q132071673	exact
Turtle Rises	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Turtle Rises`	close	Attested source name. Fifth of the Nine Ways: the receiving partner face up with both knees bent, pushed back by the partner until the feet reach the chest, with deep entry and deep and shallow strokes kept in measure. The text calls for deep entry and gives no warning about depth, so the caution this record attributes to it is not in the source.
Twining Position	Historical sourceKama Sutra	`Veshtitaka (the twining position)`	close	Attested source name. The receiving partner's thigh laid across the penetrating partner's. Burton fixes only the crossed thigh, so the side-lying, face-to-face staging with the thigh carried up to the hip is the catalog's reading.
Viennese oyster	Historical sourceKama Sutra	`Piditaka (the pressed position)`	close	Attested source name. The full press that follows the raised forms in Vatsyayana's sequence.
Viennese oyster	Knowledge base	Q1061018	exact
Widely Opened	Historical sourceKama Sutra	`Utphallaka (the widely opened position)`	close	Attested source name. Burton renders it as the receiving partner lowering the head and raising the hips. He gives it as one of the Deer-woman's ways of lying down and leaves the partner's posture open, so the partner lying over is the catalog's staging.
Yawning position	Historical sourceKama Sutra	`Jrimbhitaka (the yawning position)`	close	Attested historical name for this position in the named source; the source wording may describe a variant of the general form.
Yawning position	Historical sourceSu Nü Jing (Classic of the Plain Girl)	`Phoenix Soaring`	close	Attested source name. Legs raised wide while the partner kneels between.
Yawning position	Historical sourcePersian & Mughal erotic miniatures	`The reclined union`	close	Attested source name. Legs-raised reclining scenes recur across the Safavid and Mughal albums.

Method, and what it does not cover

tag existence and deprecation: All emitted tags, primary and support, were checked against the live tag API. None is absent from the permitted vocabulary and none is deprecated.
wiki sense checks documented: 46 of 104 rows carry a recorded wiki check with a verbatim quote. The remainder were mapped without a documented wiki read. This crosswalk should not be described as wiki-verified end to end.
method: Mappings were produced in batches, adversarially verified by an independent reviewer per batch, then swept for completeness. Rows flagged by the sweep were re-settled against tag wiki text and independently adjudicated.
additions: The statements above describe the 104 positions mapped on 2026-08-09. The 115 positions added on 2026-10-12 were mapped the same way, in batches of about ten: every tag, primary and support, was checked against the live tag API (present, used on at least one post, not deprecated); each primary tag's wiki page was read and the sentence relied on was recorded verbatim in the drafting notes, except for tags whose wiki page is empty, which are listed under undocumented tags; and an independent reviewer per batch re-fetched every tag and tried to refute each row. Rows the reviewer rejected were dropped. The 2026-08-09 tag pool and its counts were not used for these rows. No row uses a tag that refers to age, youth or a childlike body.
support tags: Support tags reconstruct structure that the primary tag discards. They are not a restatement of the act and are not quality or style tokens.
surface: on_bed is emitted wherever the position support_surface is a flat bed regardless of the figure posture, so the surface axis is carried uniformly. Read it as a scene-surface assertion rather than a strict posture claim.
camera tags: Image-composition tags are excluded from support sets except where the position is genuinely a camera-relative one. from_behind appears once, on the single solo row where the rear three-quarter viewpoint is the intended sense.
parent child: A tag may be exact for a parent position and broader for its catalog children. That is SKOS hierarchy, not a collision.

Undocumented tags. These tags are live and not deprecated, but their wiki page body is empty. No claim about their extension beyond the plain sense of the name is sourceable, and rows using them are held below exact. upright_69, pelvic_thrust, hands_on_bed, grabbing_another's_hand, reverse_piledriver_(sex).
