So...this is pretty embarrassing for me to admit but Ive been having trouble performing the last few times my girlfriend and I have been in bed. To start things off I'm in my early 20's. I have a clean bill of health, and I'm pretty physically active. So my question is sence there seems to be no physical problems with getting an erection what is the problem? My girlfriend is very attractive and there's no doubt the feelings are there for her. It's not anything she is doing wrong but she does try to blame herself and that makes me feel worse. Could it be from stress or performance anxiety? Please help. Your feed back is very much appreciated and I hope this is in the right place.
