It’s the “up-and-outer” that worries me. The guy who, right after sex, is up checking his messages, organizing his CDs or talking about all the work he has to do and the busy morning ahead. Just as women experience post-orgasmic regret, men experience pre-orgasmic anticipation. Men will say all sorts of things and get themselves into all sorts of situations and lower their standards in ways that women cannot fathom just to have sex, so powerful is the desire for orgasm (and why the aging toothless prostitute is still able to turn a tidy profit).

Hence, right after sex, many men experience their own form of post-orgasmic regret, a sense of entrapment and desire to flee. Some anthropologists argue that this in an evolutionary response—women have a limited amount of eggs and men have an unlimited amount of sperm. So women are going to be choosier about whom they sleep with while men are going to be more indiscriminate, and then consequently want to get out when they’re with a woman with whom they’re not interested in mating with. So let’s cut to the chase. He may be saying all the right things, but his actions and sexual signals post-sex may be saying otherwise. Cherish the cuddler, retrain the rollover-er and when it comes to the up-and-outer, beat him to the door and don’t look back!
