Sex

Simply because foreplay implies that it's just the starter, with penetrative sex being the main course.

Sex play can be a sensual feast in its own right, and shouldn't just be seen as something you do to get to the main bit.

After all, how can you really enjoy it if your mind is on what comes next?

And don't forget the play part of sex play.

Great sex has a sense of humour. After all, rubbing body parts together in a frenzied way could be seen as a slightly ridiculous thing to do.
