It probably doesn't happen often, but once in a while, you might find yourself in need of a reason (or excuse!) to have sex.  For those times, you'll want to have Kheper Games' 40 Reasons To Have Sex handy.

Inside the box, you'll find forty cards spelling out (and illustrating!) a funny reason to get sexy, like 'She slid into your DM's to get you to slide into her' or 'You've just been voted head cheerleader.'

Pick a card, display it on the included stand where your partner can't miss it, and let the games begin.
