I just dont get it, and its killing me, I get hard and stay hard when we are making out, when I am playing with her, and even when she is rubbing me with my pants on, but the second I take it out, i just start thinking about everything that could go wrong and then I lose my erection, thankfully I am pretty good with my hands, so I can still make her orgasm, but I really want to be able to have good actual sex, and I dont know how to fix this.
