We've been together for 3 years now.We've lived together for almost 2. I love him. I don't doubt his loyalty and I know he loves me. We used to have sex all the time, fun sex everywhere, romantic sex, but for the past year we never do it. It's July already and we've only had sex three times! That averages about once every two months. I hate it! I've tried desperately to talk to him about it, he just says "i don't know" even when I'm sobbing. I've tried to talk on several occasions and it never gets me anywhere! I'm so frustrated. I feel so unwanted, undesirable, and depressed. I've tried everything to fix this. Romantic weekends, seduction techniques, surprise sex, nothing has worked. When I do manage to convince him to have sex it lasts for about three minutes and I'm always left unsatisfied. I know he isn't gay, I know he's not cheating. I... I just don't understand what I did! I can't fix this, I've tried! Someone please help me, Idk what to do anymore...
