Why go through all the work just for sex?

Yeah you should leave her. She is using sex in a very unhealthy way.

As long as the points are redeemable on demand (or able to reserve a time with short notice) for a variety of "acts" and they aren't too hard to earn, it sounds like a win in disguise. You get to put the points to what you want when you want and, you get the bed to yourself while earning them. And when she want's something from you put her on a points system (missionary=1 point anal=5 points with extra fractions for enthusiasm and performance and a sliding scale for anything in between). She want's expensive new shoes 500 points. A nice vacation 25,000+ she has to earn 250 points while on vacation :P etc.

Maybe you should have done your part..

This can go both ways, either your wife is putting you through cruel and unusual punishment, or it's a way of her telling you that you aren't pulling your weight in the household, which then YDI.

That's one of the saddest things I've heard. She turned something that is supposed to be beautiful and intimate between two people, and turned it into a petty reward system.

No offence, but that sounds more like an ex-wife than a wife to me. If she does not grovel an apology then you should be going elsewhere. You are worth far more than a bitch who would do that.

Well good luck OP!

Doesn't she enjoy sex too? Or does she only use sex to make you do chores?

By that logic sex is solely a reward for you and you're under no obligation to try and please her during.
