sex problems

you know that feeling when you really just want someone to pay attention to your wants? take time out for you? well, I definitely do. my fiancee and I haven't been having sex. he has no sex drive. I have a very high one. it's to the point where I can't help but cry when he turns me down. masturbation doesn't do it for me either. I just want to feel attractive again. I've talked about it with him, I've tried everything. but it's not working. my heart is breaking over something I never thought I'd cry over.
