Where to start. I'm 25 year old guy in good health. No major health problems currently or in the past. The trouble I've been having lately is that I can't seem to reach orgasm through any type intercourse. In fact I seem to experience a general lack of sensitivity in general. I have no problem getting and maintaining an erection, it just doesn't build. I'm not on any medication and honestly can't think of any issues that would cause this. My wife says it's all in my head, says I'm worried about knocking her up, but I don't think that's 100% true. Even when she gives me a blowjob it sometimes won't work or if it does it takes her quite a while of wailing away on me. It seems lately that I'm becoming less and less interested in sex as well. I don't know if this the problem worsening or simply just because I'm tired of never getting off when I have sex and also having to hear my wife complain about how I never get off. People have suggested that I have low testosterone levels but while I haven't had blood-work done I don't think that's the case. I'm big into lifting/bodybuilding and have continued to make gains on top of not displaying any other symptoms of low test. I'm just getting pissed off now and near the point to where I'm just ready to give up. Sex just isn't fun anymore. I'm thinking of heading to the doctor but figured I'd give this a shot to see if anybody had some suggestions as to things I might try. Any help will be greatly appreciated and I can provide any further information if needed. P.S. If it helps I've never been extremely sensitive. Even on my first time I wasn't able to get off. It took me a few more times, I think mainly to get relaxed and comfortable before I could. Just an afterthought I figured I'd throw in.
