Hi,

I am a 21 year-old healthy male. I am in my third year of college. I haven't had sex since I have been to college and I think it has taken a toll on my mental health. I had 2 sexual partners in high school and never had any mental health issues. With both of those girls, I had problems getting an erection when we first tried having se, but they both gave me several chances, and I eventually overcame the problem.
Since I have been in college, I have not had sex, but I have had no less than 6 girls lying in my bed, naked, wanting me to have sex with them and I have been unable to get an erection. Perhaps it is the casual sexual environment of the college I go to, but these girls did not give me multiple chances to get an erection and all ended things with me quickly. I think all these failures have taken a major toll on my self-esteem. Nowadays I don't pursue girls near as much as I used to because I know the failure is inevitable once I get them in bed. Being around friends that have multiple sexual partners doesn't help either. I am seeing a psychologist and have told him all this, but I haven't been able to stop being depressed.
I have the feeling in the back of my head that if I was able to break "the curse" and finally have sex again, all my mental health issues would go away and I would have some confidence. I don't know if it will ever happen, though.

What do I do?
