Always want sex at the wrong time...

Why do I always want to bed when we can't!!! It's torture for me and my poor husband and it happens every cycle!! I feel bad for the poor guy, I'm hardly ever horny without him having to work for it and the only time I am he can't get anything out of it!! Poor guy, he's such a good sport about it thank goodness! Anyone else have this problem?
