Hi everyone! I'm a little curious if it's possible to have a change in sex drives abruptly? I'm 22, living with my boyfriend (he has his own room too) along with 3 other people and it's our first year living together as a couple rather than friends. To get to the point, we don't have sex at all anymore. Before May we had sex constantly, at least once a week and now the last time we did it was maybe 2-3 months ago? and even then it just seemed forced and it felt awful. I understand that it gets old and not as exciting but he can't even get it to stay up! I talked to him about this and he told me that he's just not interested in sex anymore. He tried looking at porn and that did nothing ofr him either. He doesn't masturbate anymore either. The only thing that I can see that inhibits sex is that he's so focused on himself (doing well in classes, focusing on things he wants to do) right now that he doesn't think of anything else. I'm kinda sure it's not me since he did say he's still in love with me and he's attracted to me...but at the same time...I don't get how he can say that if he can't physically respond to me. I try not to pressure him much about it and I'm trying to cope without it, but it's just such a difference from what it was from before and I feel as if he just doesn't truly want me. Sorry for the long story but your thoughts are appreciated =)
