I'm having the same kind of issue. Im 19, and my boyfriend is 34. We've been together for a little over a year. Our sex life was amazing for the first couple months, then it slowed doen and now it seems we haven't had sex in two months. I've tried everything... new lingerie, oral all the time randomly, compliments all the time, just touching him in a seductive way, kissing him, trying to have sex in new places or the usual, nothing works. He says he's always to tired. I'm afraid he's not attracted to me anymore. He never looks at me with desire despite what new sexy panties or bra I buy, or even completely naked. He says he is but never shows it. Its very crushing to my self esteem, because I once believed I was hot.. but now I'm not so sure. I don't know what to do.
