I'd never choose not to have sex with a man because of his penis size. Chances are if i've got his pants down he's tickled my brain and he has other features that have peaked my interest in him. I just happened to marry a man with a large penis. I was attracted to him before i ever saw what he was packing. I have been with men of all sizes, including pretty small, and i never got up and decided not to have sex if i was interested before the pants came off. Maybe there are some shallow women out there who would pick a mate solely on penis size, but many of them have higher standards than just penis size.
