Man is the constant problem between men and women. I don't know why God made man so horny and the woman so able to do without sex. Or it seems that way a lot of the time. I would say that you both need to sit and talk, and you need to explain to her how often you need sex and how it makes you feel when she acts like she is going to have sex and then does not. It makes you feel so rejected, I know. It may be that she is rejecting sex with you because you are not meeting some of her needs. That's what you need to find out in your conversation with her. It may be that you just need sex more than she does and that you may have to masturbate some of the times when she is just not in the mood. I know one thing, arguing about the situation is certainly not going to make sex more available or the mood for sex more inviting. If you have to go to counseling do it. Good luck.
