My boyfriend and I were having sex for the first time and he was a virgin so he was really nervous. He wore a condom and the sex was amazing, we checked it every so often to make sure it didn't rip or anything. But after a while I felt like he kept getting more and more nervous so much so that he didn't even cum. He checked the condom to see if anything was in there but there was nothing so I'm just wondering is it me or is it possible for him to be too nervous to cum?
