I am in a long distance relationship where I do not get to see my partner very often. Last month, she was in town for 4 days, so we spent all 4 days together. On the first day, we had sex 4 times, the next day we had sex twice and on the third day we only had oral sex.

We tried to do it the third day, but I was unable to reach a full erection. Well, thats not entirely true. During the foreplay, I had a full erection, but after I got my condom on, I started to lose it. Ive never had a problem with condoms, it was the same brand/type Ive always used. The fourth day I was also unable to perform. I think it may have been because of what happened the day before, but it was frusterating for me, and it made her think that I was no longer attracted to her.

Im only 21 years old. I do not do drugs or smoke, although the third night I did have a few drinks, and I was a bit tipsy. I am a bit overwieght, I dont know if that makes a difference or not though. I read a few other threads about being nervous and how that could stop someone from reaching a full erection, but the first time it happened I wasnt nervous at all. Im wondering if I should be seriously concerned about this, or what.

Ever since that, she has had a few talks with me because she doesnt believe that Im still attracted to her, or it was something about her that made it happen, and Id just like to be able to quell her insecurities.
