my boyfriend never wants sex when I insinuate it?

Obviously it makes me feel horrible about myself. Whats wrong with me?

Maybe it's not because of you.

The lack of desire for sex in a relationship shows there is some problem..

Besides sex how is your relationship?Are you happy together?Or do you argue often?

Is he ok with sex?Maybe he doesn;t have experience and he feels some stress about it or he is embarassed about it?You know it happens to very young people

Is his sex drive lower than yours? Or do you initiate it about as much or less than he does? How do you initiate it? As in, do you say something, or do you start being flirty and physical, or what? Does he always just say no or does he sometimes go along with it?

It could just be that when he's not in the mood, he's just not. Going to generalise here, but this is usually found in reverse; that guys have girlfriends that are often not in the mood when they are. It's pretty hard to guess though, it could be so many things. The fact that he denies it is interesting though, how exactly does he do that? Does he say he does go along along with it when he actually doesn't?

Could be a control issue. Could be tired and or stressed.

I'm a guy who often rejects GF when she initiates sex and I know it makes her feel horrible. The problem is the way she initiates it. She'll come up to me and immediately start fondling around and implying that I need to be doing certain things and I find the whole experience crass, rigid, forced and generally not sexy in the slightest. These days she has learned to play hard to get a bit, and when she wants sex now she'll usually tease a little and make me feel like I want to chase her. I guess it is the thrill of the chase I still enjoy.

Obviously this may not be the case with your boyfriend, but my advice would be to experiment with different approaches to initiating sex until you find one which he likes.

I get flirty and physical. He'll deny it by just saying its ridiculous and then change the subject.
