Excitement and nervousness can go both ways on erection. I once was with at the time what I thought was the most beautiful girl ever I had been with. I wanted it so bad, that no matter what was done by her or me, I couldnt get hard. Eventually with ginseng,gin and juice, and then benadryl I was able to. It wasn't any of those products though, it was all in my head. Don't worry bro, you will be fine. As you get more comfortable you will be ready.,,,,7
