Hey guys, first post.
Yup, the title sums it up pretty well. When I have sex with my girlfriend, I can't ever cum, and sex ends when I go limp. I've always been really upset about it, but lately my girlfriend has been taking it to heart, believing that it's somehow her fault (i.e. she isn't hot enough, she's too fat, she isn't doing the right things for me) and it's especially frustrating to her if sex is short. I honestly do not believe that it's the issue, but I really can't seem to convince her. I'm pretty sure that it's a problem with my body, or that I simply can't cum around another person. Strangely enough, I can cum on my own when nobody else is around via masturbation. It's really sad because she's a beautiful girl who I'm in love with and can connect with on so many different levels, but this is a major obstacle in our relationship that I'm worried I won't ever get over. Does anyone have any experience with this, or know of a partner that has the same problem? I don't know what to do, I feel useless and it makes me want to kill myself sometimes.
Please help.
