I'm 19 years old and having a problem. I'm a virgin, and with a new girlfriend. Before we got together I would get erect from just hugging her close. Now we've been apart for a few months (summer break) and we recently visited each other. We kissed each other for the first time then, and fondled each other and got undressed and such (no actual sex though). The problem was that I couldn't get erect at all while I was doing anything... kissing her or her body. She had to give me a hand job to get me erect. What's happened to me? I can still do it through masturbation because of the stroking motion but I just can't get it up when I'm with her now without help. I don't feel anxious, either... What's going on?!
Sounds like nerves to me, too. It should not take you long to get past this. Try not to stress out over it, as stressing can make it worse. Relax and take things as they come, and the situation will take care of itself.
