Sex positions
How can you use pillows to explore sex positions with more comfort?
Where the pillow goes (pelvis, knees, lower back, nape) and what to avoid: the face.
Short answer
A pillow changes an angle or removes tension at one point. One, and firm. If it sinks, slips, or makes you tense up, it is not helping: take it away.
There is no correct placement. A pillow does not demand penetration.
One change at a time, firm before soft
One change each time. If you move pelvis and lower back at the same time, you will not know what is doing what. Firm holds; soft gets eaten and pushes the neck or the knee somewhere you did not intend.
Stable base: bed or floor. Not on a slippery edge. If there are fluids, a washable cover or a towel on top; the living‑room cushion does not go straight to the bed.
Under the pelvis or sacrum
On your back, the pillow goes under the sacrum, not blindly under the lower back. It lifts the pubis slightly. It changes the angle of penetration or leaves hands freer. It does not replace friction or a hand on the clitoris.
If the lower back hurts, move it towards the coccyx or remove it. The person on their back can take it away and stop.
Between the knees, on your side
On your side, the pillow goes between your knees or under the upper knee. It lines up hip and lower back. In spooning, that is the support; the name of the position does not do the work.
If the upper knee falls and pulls on the hip, the pillow is too soft or too far back.
At the lower back
Back against a headboard or a wall, the pillow fills the lower‑back gap. Feet remain on the floor. In lotus, that is back support; you do not need a stack.
If it pushes you forward or makes you hunch, lower it or take it away.
At the nape, for oral
The receiver, on their back. The pillow goes under the nape, not shoved under the shoulders: it lets you see and breathe. It is not a pillow under the pelvis by another name.
If your chin ends up against your chest or your neck hurts, lower it or remove it.
Under the knees or the chest of the giver
Giver: pillow under the knees if kneeling, or under the chest and shoulders if lying face down. Weight goes to the pillow, not the neck.
If the chest pillow pushes the jaw backwards, change it. The giver turns their head and stops.
Chest or shoulders, never the face
In a prone doggy style, the pillow goes under the chest or shoulders of the person face down. The face stays free: turn your head, breathe, talk. Never under the face or against the mouth.
If the pillow covers, presses, or prevents turning the head, out. Stopping is not a failure of the support.
Barriers and when to stop
A pillow does not change the risk of pregnancy or sexually transmitted infections (STIs). A new condom for each act of vaginal, anal, or oral sex. When moving the pillow, check the barrier.
If something hurts, tingles, makes breathing hard, or the pillow moves, stop and remove it.
