So I have been seeing this absolutely georgous girl. We get along very well, and everything is going fine. We actually have had sex twice already, but when we do, i have a hard time getting an erection. once i get one, its all well and fine, but i think it is making her think i am not that into her. this has never happened to me before, so i am kind of worried. even last night, we started fooling around, we started dry humping for a little bit, and i started to get aroused, but not very much, and she started rubbing my cock but it didnt really get me harder, and then i started thinking about it which made it more difficult. any suggestions or ideas?
