No sexual interest in girlfriend whatsoever.
Well I'll lay out my dilemma as simply as possible:
I am 26 and my girlfriend is 23, I am the kind of person that gets compliments and women try to contact me quite frequently without trying. I don't say this out of any sense of vanity or anything like that, I'm a very humble person and I am very considerate of the feelings of others. I am finishing a very hard University degree and my career path has plenty of opportunity. I have a strong sex drive and I'm quite gifted in bedroom associated activities meaning I like sex and I'm good at pleasuring women. My girlfriends in the past have all been your standard affair; works out 4 days a week, goes to university, goes to the club on the weekends, complete psycho when she drinks and screams at me for things I have nothing to do with. Basically high ego attractive women.
My current girlfriend is on the other end of the spectrum because I felt like taking a break from women that drive me nuts, my current girlfriend is extremely nice, very soft spoken and kind. When I first met her I thought she was absolutely gorgeous but as we've been dating for about 9 months now she's gained a lot of weight and become very very lazy in her lifestyle. The effect has been I do not find her attractive at all anymore, I do not want to have sex with her because I just find she is not sexually appealing due to how she takes care of her body. That part of the brain in physically active people that tells you to get up off your butt she doesn't have, she has a high sex drive but while we have sex I just kind of feel gross the whole time. I'm happy she enjoys it and I'm happy I found someone who is finally nice but I don't know if I should carry on in a relationship where the sex is terrible and will inevitably become non-existent.
I should add that I do greatly care about her and I do feel love in the sense that seeing her sad brings me pain but I just don't know what to do. It seems like I have to choose between being sexually satisfied or emotionally satisfied.
