Today we have an assignment for those of you who sleep with people who have the same thing going on in between their legs as you do. It's an easy game that will help you get a better sense of what each of you likes in the bedroom.

Remember when you were a desperate teenager, furiously dry humping on the basement sofa in the throes of young passion? Don't leave dry humping in the dust: do it tonight.

This week's instalment of Do This Tonight is a flexible sex position that works well for a diverse array of couples. The Flipped Missionary/Butts Up looks deceptively simple, but I think it's a vastly underrated position.
