Ok, I'm half expecting sarcastic responses to this one, but whatever. Anyway, I'm usually just fine in bed with my girlfriend when it comes to getting aroused to the point where we can physically have sex, but here's the problem. I'm used to getting strong erections, and that doesn't seem to be happening anymore. It seems like I'm always "75 percent aroused" instead of being rock solid. Now she hasn't said anything negative about this, but it really could be bothering her. I know she's getting off when we have sex because she's ultra sensitive and it doesn't take much to make her climax. However, I'm really starting to worry about this, and in turn, the problem seems to be getting worse. Last week we were about to have sex, I put the condom on and pretty much went limp. I felt awful because I lied to my girlfriend and told her I felt sick......man, this really sucks. Anyway, I quit smoking some time ago, I'm in the best physical shape of my life, and I'm still pretty young. Yes, I am still able to have sex, but it doesn't feel nearly as good as it used to when I could get fully aroused. I haven't been masturbating to excess either, so I don't know what could be wrong. Please, if you have any advice, kind words, or whatever, post them here. If there are any possible solutions to this problem medically (herbal suppliments, etc) please let me know. I really don't want to go to a doctor about this, I would be very embarrased to have to seek help at such a young age.
