Love or sex?

If you're really in love, the sex should come naturally, since love requires that both of you communicate well and often. You can't very well complain about your partner's performance in bed if you've never bothered to give them directions. If you whine to someone other than your partner about sex, your brain is clearly malfunctioning. If you find yourself on the receiving end of such a lament, quickly suggest that the party in question immediately STFU and tell someone who gives a damn or, perhaps, even the person they're, y'know, having sex with? It's not that big a request, really.

I think there's equal potential for the proverbial fire to get hotter or colder as time goes on, depending on the choices both parties make and the expectations they have for the future. If the sex gets dull and you think that's just part of the natural progression, you'll be far less likely to surprise your partner with a Kama Sutra or a fancy new swing or some sexy li'l silk thang. You'll probably just whine about it to your friends, family, and co-workers.

ALL fires require constant fuel.

I think that if you continue to deepen the communication and strengthen the trust in a relationship, the sex will get progressively more fresh and inventive. That's why ten out of ten times I'd pick love over good sex.

Jam it back in, in the dark.
