I'm 25 and I'm having trouble maintaining an erection during sex for the past year or so. I have a high sex drive and often get erections just by looking at girls in public. During foreplay, I have no problem getting a full erection and I feel aroused by just mild touching and kissing.
But, I seem to start going soft when I put a condom on or a few minutes after I begin penetration. The only way I have a chance at reaching orgasm is if I start thrusting really quickly for a few minutes before I go soft.
This is very bothersome and embarrassing. Since this has become a regular problem, I now think about it every time I have sex which only makes it worse. When I do lose an erection during sex, it's nearly impossible to get hard again because I start panicking. It also leads to unsafe sex since I am often tempted to have sex without a condom.
I don't do drugs, drink alcohol, or take any meds that could cause this. I exercise often.
I do masturbate while viewing porn, but I've cut this down lately in hopes of solving this problem. I do notice that my penis is not very sensitive to the feel of a vagina...especially with a condom. I'm not sure if this is causing the loss of erection. I've thought about going 3-4 weeks with no masturbation or porn to see if this is corrects the problem.
