I am 16, I would say I have had an average sex drive in past years up until about 3 moths ago. I met someone and we have got into a serous relationship but my sex drive has seemed to wain and almost disappear. Even before I met my girlfriend, I had no driving driving desire sexually like in previous years. I had not masturbated for about a month prior to meeting her, the desire does just no longer seem to be there in its original form. I don't even get morning wood anymore, there have been very few times that i have felt truly sexually driven with my girlfriend. I would love to get back to the way I used to feel, especially as my girlfriend has a high sex drive. Recently even the littlest things; moving slightly a sound or talking have caused problems downstairs. If I stop and think about what I am doing there is no driving desire my mood seams to deflate like a burst balloon and I sink back into a truly undriven state. I'm not sure if this is a phycological or psychological problem but I am at a loss of what to do about it. I have talked to my girlfriend about it and she is incredibly understanding, she suggested I an nervous. Maybe that is true, I used to have allot less problems. But now I get nervous about nothing happening, and nothing happens witch is causing a problem of its own. Although she loves me dearly, I can see this problem is making her feel insecure about my attraction to her, even causing her to sometimes after we have had an amazing day out to think that she is not good enough to me. I truly value and love my girlfriend and this as well as her is causing me destress as I feel embarrassed and emasculated. I would really like to resolve the problem but I'm not sure how to go about it. Any constrictive help would be greatly appreciated. Thanks!
