Hi I've been going out with a girl for two months now. We both love each other and decided to have sex for the first time. It was my first time so I was really nervous and was shaking a bit. When it came to actually doing it I had a erection but couldn't ejaculate what am I doing wrong? we are both in your early twenties I hadn't done it before. I'm worried its going to happen again and think she is also worried about it. What am I doing wrong?
