TIME BOMB

You need: A clock or an egg timer.

How to play: Pick a time interval — 20 minutes, let's say. For whatever interval you choose, tease each other with kissing, touching, and other forms of foreplay. But no matter what, absolutely do not allow penetration until that much time has elapsed.

Why: Most busy couples have foreplay down to a science, or rather, a routine. "Time Bomb" refocuses you on the pre-game show, the part that used to be so much fun before you lived together. You'll be surprised by how much slowing down changes things. You get really creative and really turned on.
