Don't feel bad, this happened to me with my current girlfriend, our first time together. I am in my mid 30's and recently divorced. I have never had any kind of problems getting erections, but after getting back into the dating scene, it was like being a teenager again, I was very nervous. My current girlfriend and I were friends for a couple of years before we hooked up. I was nervous as hell, and our first time together, it just didn't happen, no matter what I tried. She was really cool about it even though I felt like a total loser at the time. But obviously, she really liked me for me, and didn't even think twice about it and told me about how nervous she was too. So the next time went much better Don't sweat it dude. Relax and enjoy.
