Dear Doctor:
About two weeks ago, I slept with my girlfriend, and lost my virginity to her. It was fun and I lasted for a long time, but I was not able to orgasm. In fact, after two hours, my leg got a cramp and I had to stop. What bothered me was that whenever she rode me or I penetrated her, I had some muscular discomfort on my leg or hips. I am 20 years old so I doubt that age is not the problem. After sex, my inability to orgasm led me to conclude that I was gay by assumption. However, after reading several online blogs, I read that there are quite a few people who have my same inability to orgasm.I was a little afraid to have sex with my girlfriend because she has herpes and while I wore a condom, I still had some fears and pulled out several times. I have a history of anxiety attacks, but I do not take anti-anxiety medication. A week later, I have the occasional "Am I gay?" panic attack due to this inability to orgasm. I have been straight for me whole life (with the exception of nominally bisexual phase, which I merely said I was bi because it got me more attention due to the popularity of emo music at the time.) My concern about being homosexual had made me test myself by staring men in the eyes to test my sexuality. Nowadays, I try to avoid men in general out of fear though when I talk to my fellow gender, I am not afraid. Recently, I also find myself less physically interested in girls, which seems to be prompted due to my fears though my girlfriend seems to be able to get me erect when she texts dirty ideas. However, nude women photographs are not as stimulating as before. However, i do not fantasize about men either. I am really concerned because I want things to return the way they were before. I really hope it is merely an anxiety problem since I have had a history of panic attacks in my life.
