It's the third date, and you know what that means: time for sex! OK, not really (unless the world really does work like Sex and the City, in which case, kill yourself), but you'll know when it's that date. The one that, rather than ending with a kiss on the cheek and a box of tissues, results in an invitation to her place for a nightcap (or an acceptance of yours). There simply isn't an exact science to the game of love (or lovemaking, for that matter), but there are some obvious moves that will ensure she doesn't want to see you ever again. So, if you really like this girl, or at the very least like slapping flappies with this girl, crack open a bottle (not a box) of wine, sit back and don't do these things. And don't call it "slapping flappies."
