The Slide
Also called: Lying flat on top
The partner on top lies fully stretched out along the other, chest to chest and legs straight. Movement is a slow glide rather than a bounce.
One partner lies flat on their back with legs straight and slightly apart. The other partner lowers down on top of them, face to face, and once connected stretches their legs straight back, either together between the bottom partner's legs or resting on top of them. The top partner's forearms rest on the bed beside the bottom partner's shoulders, which keeps faces close enough to kiss and takes some weight off the chest. Instead of lifting up and down, the top partner slides their whole body a few inches forward and back, so the pubic bones press and rub with each pass. Keeping the top partner's legs squeezed together makes the fit snugger; sliding a little higher up the body puts more pressure where the bodies meet and less on depth.
Steady, full-body contact and the kind of grinding friction many people need to finish. It's quiet, slow and easy to hold for a long time.
A pillow under the bottom partner's head keeps their neck comfortable. The top partner can take more weight on their forearms if their full weight feels like too much.
Think of it as the on-top version of the coital alignment technique: small, rhythmic slides beat big strokes every time.
Agree on it before you try it, use plenty of lube, and either of you can stop at any point. This guide is general information, not medical advice.
