Jacking off cause of not being able to have an erection?

[Drewster1234]

So it was my first time attempting to have sex with my girlfriend and I'm 18. I've always been able to have an erection around her when we cuddle and stuff but we've haven't had an opportunity to have sex until now. I had planned it in advance and was really nervous about it. Nervous that I would be good enough and that it would go well. I had jacked off the night before and the day of at around noon. This all happened at about 5 pm and for some reason I just couldn't get an erection what so ever. It was the weirdest thing. I've never had problems getting erections until now and I'm nervous this would happen again. She didn't make a big deal out of it which was nice but I'm so embarrassed. It was my first time but definitely not hers so maybe I was just nervous that I would be good enough and I just couldn't perform. Or maybe it had to do with the jacking off and I just wasn't excited enough. Any thoughts or things I can do to stop this from happening. Maybe like some herbs or something. I do football and it's not like I don't get my workouts in. Please help

Seriously, when she was nice about it, that is because she wasn't worried or bothered.  Sometimes guys don't get an erection.  Certainly jacking off 5 hours prior to the event could have an effect, but it was most likely your nervousness and performance anxiety that killed the fun.  Don't worry, it will happen another time, just relax.  Sex is a pretty natural process.
