Both me and my girlfriend are both virgins, yesterday we both agreed that we wanted to have sex. The issue was that when we were both undressed, my erection went away faster than you can snap....obviously we were both frustrated at the fact and I was only able to get a partial erection during the 30-40min of trying...me looking stupid and her feeling like it was her fault that she did something, we both just gave up and agreed to try again another time... She feels bad. I feel stupid. WHAT THE HECK HAPPENED?!?! I just DONT get it! The time when I should have one, i dont.. and when were fully clothed fooling around or in the pool fooling around its like....really?:ugh I have no idea what the issue was..and neither does she...I just feel like an idiot...any ideas on what happend or any answers as to WHY?!
