Frottage

Frottage is body-on-body rubbing without penetration — cock against cock, cock against thighs, cock between cheeks or in the cleft without going inside. The act has its own committed audience and the tag pulls every scene where it gets real screen time, either as foreplay before penetration or as the entire focus. The non-penetrative angle is what defines the content here. Some scenes use frottage as the slow build before the act moves to anal or oral. Others stay locked on it from start to finish, with the eventual finish often happening from the friction alone. Cock-against-cock rubbing, intercrural sex with the cock between the partner's thighs, and the slow grinding that turns into a release without ever going inside all live under this tag. The performers who specialize here are the ones who can let a scene build at this pace without rushing toward penetration. Patience and chemistry carry the content more than position variety does.
