The Spider: face-to-face double crab sex position

He sits on the floor leaning back on his hands instead of holding his hips up in a bridge.

With his buttocks on the floor he no longer has to hold a bridge, so the effort on his wrists, shoulders and lower back drops a lot and the position becomes far more stable. She does most of the moving by rocking on his pelvis. It is the best way to start.

1. He sits on the floor with his knees bent and leans back on his hands.
2. She sits astride his pelvis facing him, with her feet on the floor beside his torso.
3. She leans back onto her hands, arms straight.
4. She rocks and slides her hips while he stays still or makes small movements.

Each partner lifts one hand off the floor and they grip each other by the hand or forearm.

Holding on to each other creates a counterweight: by pulling gently, both can lean back a little further and control the distance between their bodies. It adds a sense of connection but makes balance harder, as each person rests on only one hand.

1. Start in the basic Spider, both on hands and feet.
2. Each partner shifts weight onto one hand and lifts the other.
3. Grip each other firmly by the hand or forearm.
4. Move slowly, pulling gently against each other, and let go and put the hand back down if you feel unstable.

He holds his bridge still and she sets the whole rhythm by sliding and circling on his pelvis.

With only one person moving, the pair is much more stable and the risk of the penis slipping out falls. She can choose slow circles or short slides at the angle she likes, while he concentrates on keeping his hips steady.

1. Get into the Spider and check that both of you feel steady.
2. He holds his hips still at a comfortable height.
3. She moves her pelvis in small circles or slides forward and back.
4. Switch roles or rest as soon as anyone tires.
