We're dating 2 years, I'm 33 she's 24. I always initiate sex, she never does and I feel unwanted, I don't feel sexually desired. I'm not ugly, I take care of myself, we talked about this, she said I'm faster to initiate. I asked her if she was cheating on me and having sex with other guys, she was upset and we almost had a fight. But what in a world would I think?! I'm tired of her low sex drive. We talked about this a thousand times, she said I'm always complaining about her and she asked why I'm with her, because she's trying to please in every way but I'm too demanding and never satisfied with us. She doesn't orgasm, I feel like a loser! First time we discussed this I asked her if she had orgasm before, she said she had once with a guy in the past! I freaked out of insecurity! We have sex, she's horny, she feels pleasure, always wet, I'not a bad lover because I do a lot of foreplay, oral, masturbate her, use sex toys, vanilla sex, rough sex, etc. My girlfriend is on the pill, I know BC pills can affect her sex drive, my ex girlfriends had orgasm and I never felt like this loser before, even though some of them had a lower libido than mine. I dont know what to do anymore, I'm thinking about breaking up. Next week is our Anniversary of 2 years together and I'm feeling so sad about my relationship. I love her, I'm crazy about her but. Do you guys think she's cheating on me? By the way, I'm in therapy! Any advice?
