I am 18 years old and I just recently broke up with my high school sweetheart. We were together for four years. I couldn't pry myself off of her, when we were alone I mean. I could just hug her and get aroused. Lately I've been trying to move on and get with other women. I felt very attracted to this one girl in particular, one thing led to another and we were at a party hooking up. As soon as my pants came off I lost my erection. I've never been so embaressed in my life. Everytime I get intimate with a girl I will become aroused and erect but then I think "ok I've got it. but what if it goes away. I cant be like that around a girl again." and i lose it......I'm too afraid to even try again. I'm leaving for Marine Corps bootcamp in a month. I just want to leave with a healthy set of mind. Whats goin on here?
