I am a 19 year old male. I have had a girlfriend for about 6 months now and I am crazy about her. I lost my virginity to a girl who I cared nothing about and I regret it. It wasn't even that great. I seem to have little to no interest in sex. I masturbate maybe once every 3-4 days. I care about my girlfriend VERY much. It seems, however, I only want sex to make her happy. When we are doing it, I can hardly ever get off (maybe twice in the 6 months) and I get bored of it so we wind up stopping. When she tries to get me off (hand or mouth), it doesn't really do anything for me. It seems like I have to do it myself in order to get off. I also hate to perform oral on her. It just seems weird to me that I have no interest in sex what so ever. What can I do to fix this? Thanks!
