I was dating this guy for a few months, and when we finally decided to have sex, he wasn't able to get it up. Now I know that this is an embarrasing situation for the male, but what exactly could have gone wrong?
He recently hurt his knee pretty badly during while playing a football, and he blamed it on the pain in his knee. But i was talking with my girlfriend, and she says it's because he was nervous. Now I don't know if I believe that, because he's been with many girls... and I would have never expected him to not being able to errect, because he had in the past...
Any thoughts?
