I'm 23 years old- (6'3, 185 lbs). In shape, healthy, no stds.
I've started seeing this girl who is incredibly hot. We've been dating for a couple weeks and last week we came back to my place. We started making out, touching etc. and I was completely hard- no problem. Once the sex came up (getting the condom on, positioning myself) I had trouble staying hard.
I explained it wasn't her and she understood. A few days later the same thing happened. My penis stayed hard enough for me to penetrate her although I couldn't go long at all and I wasn't extremely hard inside of her.
I haven't had sex in a while (about 4-5 months before her). Though I've never had problems masturbating (I usually masterbate 3-5 times a week). I'm hoping it's just performance anxiety.
Can anyone help me out here? I really like this girl and I want to fix this problem.
