The Crab: face to face, her half-reclined and him kneeling

The Crab is a face-to-face position with vaginal penetration in which she is half sitting up rather than lying flat. She leans back on one elbow or hand, stretches one leg out along the floor and keeps the other knee bent with the foot down. He kneels upright astride her straight leg, leaning towards her, so their faces stay close enough to kiss. Penetration is shallow and he sets the pace.

Illustration of The Crab: Face-to-face position on the floor: she half-reclines on one arm with one leg stretched out, and he kneels upright astride that leg, setting a gentle pace.
Anatomy and biomechanics

She sits back on her buttocks with her torso raised, propped on one forearm or hand behind her. One leg is stretched straight along the floor between his knees; the other is bent, with the foot flat on the floor beside his hip. He kneels astride her extended leg, thighs low and shins along the floor behind him, torso upright and tilted towards her. His hands are free: he can hold her waist, her bent knee or her back. The scissor-like position of her legs limits depth, so penetration stays shallow, and he controls the rhythm with small movements of his hips. They face each other, can look at each other and kiss. The load falls on her supporting wrist and on his knees.

Why this position works

Some couples like it because it combines closeness with a different angle: they are face to face, close enough to kiss, but she is sitting up rather than lying under him. The penetration is shallow, which some people find more comfortable or a good change of rhythm, and his free hands can caress her or add clitoral stimulation. She can also use her bent leg to draw him closer or hold him back. Sensations vary from person to person.

Variations of this position

Variation 1: she leans back on both hands

Instead of one elbow, she props herself up on both hands behind her, arms straight, with her torso more upright.

With both hands on the floor her weight is shared between two wrists, and her torso rises, bringing her face closer to his. It frees neither of her hands, so caresses are up to him. Her pelvis can rock slightly to meet his movements.

  1. Start in the base position, with him kneeling astride her straight leg.
  2. She places both hands flat on the floor behind her hips, fingers pointing back.
  3. She straightens her arms until her torso is fairly upright.
  4. He holds her waist and moves gently while she rocks her pelvis towards him.

Variation 2: her bent leg around his hip

She lifts the foot of her bent leg off the floor and wraps that leg around his hip or lower back.

Her straight leg stays between his knees, but the bent leg now hugs him. She can pull him closer or slow him down with her calf, which gives her a share of control over the rhythm. Body contact increases; depth stays limited by the scissor of her legs.

  1. Start in the base position, with her propped on one elbow.
  2. She lifts the foot of her bent leg off the floor.
  3. She rests that calf on his hip or the small of his back.
  4. She uses the leg to draw him in or hold him back while he moves.

Variation 3: cushion behind her back

She leans back against a firm cushion, the sofa base or the side of the bed instead of holding herself up on her arm.

The backrest takes the weight off her wrist and shoulder, so she can hold the position longer and use both hands to caress him. The angle of her torso stays the same, so the mechanics and shallow depth do not change. It is the most comfortable option for longer sessions.

  1. Place a firm cushion or bolster on the floor, or sit with your back near the sofa base.
  2. She sits back against it with her torso half-reclined, one leg straight and the other bent.
  3. He kneels astride her straight leg, as in the base position.
  4. With both hands free, she can hold his waist or shoulders while he sets the pace.

✓ Tips
  • Put a cushion behind her back or under her supporting elbow: her wrist and shoulder carry part of her weight.
  • Switch the supporting arm from time to time so the same wrist does not tire.
  • He keeps his torso upright and moves from the hips; leaning his weight onto her makes her support arm give way.
  • A folded blanket or a mat under his knees helps on the floor.
  • Penetration is shallow by design: small, controlled movements work better than long thrusts that make him slip out.
  • Use lubricant if needed and a condom to protect against STIs and pregnancy; stop if anything hurts.

Frequently asked questions

Is this position suitable for beginners?

Yes, with some practice. It needs moderate effort: she holds herself up on one arm and he stays on his knees. A cushion behind her back makes it easier.

Who controls the rhythm?

Mostly him, with his hips. She can guide the closeness with her bent leg and her free hand.

Why is the penetration shallow?

Because her straight leg runs between his knees, which keeps their pelvises at an angle. If you want more depth, it is better to switch to another position than to force this one.

Can we kiss in this position?

Yes. Her torso is raised and his leans towards her, so their faces are close.
