This is embarrassing, but oh well. I'm 18 and I've had a few sexual experiences. First when I was 13, and I couldn't get it up. I believe that was just because I was extremely nervous. I've had more since then and I've had this problem maybe 50% of the time. I've definitely gotten it up for a few girls, but a few occasions have been red faced endings. When I'm watching porn I have no problem, duh. I'm not sure if it was the mood (if that even applies to guys,) the fact that I didn't have feelings for the girl. What ever it is, I'm not cool with this problem. I'm a confident person so that isn't really an issue, I just don't get it. Any advice?
If you had a super dirty dream that your alarm clock interrupts, this is a way to "finish it off" (so to speak)
