Hello im 16 and when im with my girlfriend i sometimes have erections and sometimes i dont. The first time i was with her i was very anxious and nervous we did not have sexual intercourse but i wasnt erect. Ever since then ive always been anxious and nervous when im with her in case i dont get an erection. the other night i was going to have sex with her for the first time and i was erect then suddenly i wasnt and obviously it didnt end up happening. I was just wondering is it just my anxiety that is contributing to my erectile disfunction?? and i wanted to know how to get rid of my problem?? so i can go back to enjoying being with girls because this is really starting to suck
