Tonight, I was fooling around with my gf, hard as a rock for AGES, and then when it came to the moment of truth, I just couldn't get fully hard. This is really depressing the shit out of me. I'm not worried about what she thinks, she was cool about it, but this is really gonna fuck with my head, especially with my college exams coming up next week. It all seemed so rushed (we're both virgins). Maybe next time I should just chill. I dunno... Is this normal?
