Man up... those two balls hanging between your legs are what you call testicles.. If you want it, go for it, but don't go for it in a wishy washy maner.. but with some Balls! If you ever feel nervous.. and that lump coming upyour throat... bite down and face it... make it a thrill, because if you want her.. you're going to want every part of her... and that'll make you happy..
Have ever been afraid of something that made you happy?
Only thing I can say, is be comfortable, because if you are, that my friend is you, and you is the only person you can be well.
So.. if she doesn't want to play with your marbles... spread some peanutbutter on em and let her dog lick em...
Good luck partner
