Dude.........You get an erection from jerking off right? So you dont have
a physical/biological whatever you want to call it problem.
I know what your going through. I never had no injury to my balls but I know what you are going through. When I jerk off I get hard immediately.
But with chicks its a whole nother ballgame. I get performance anxiety.
I think thats what you have.
My only solution to this problem is taking viagra. But now im scared
because they say u can go blind from taking viagra.
I think the only solution for you......Is to not worry........Take your time.
After you make out with the girl a few times and get comfortable with her you will eventually not be nervous and you will get hard.
