I don't mean to single you out, but I remember in another thread you mentioned something to the effect that while skill is more important than size, that after being with a guy with both skill and a huge dick, it's hard to go back.
Now, I don't think most women are in that same boat as you (This is a big dick site, after all, what do people expect?), but speaking for myself and a lot of other guys, I'd be pretty devastated if a woman considered me "tough to go back" to over a physical trait I couldn't help, at least in the context of a serious relationship. To me, the idea of being outright rejected by a size queen after a casual one-off is far less upsetting than the idea of being in an LTR or even married but forever being second-rate at giving intimate pleasure to the woman I love compared to some other guy she'd been with as a result of his monster schlong. It's scary on a visceral, primal level. At least a rejection is no skin off your nose if there was no commitment to begin with, and a guy is free to find another gal who prefers what he has or who just doesn't have a preference one way or another.
The idea of that happening used to really scare the hell out of me before I had sexual experience, even though I'm what I think is just about ideal for women in general (6.5x5), so I can really see where these somewhat smaller guys are coming from with this fear. It's why these guys can hear 100 women say "Size isn't important as long as you're in the normal range and not too big or small" but will get bent out of shape over the one woman who says a huge dick can give her more pleasure than a normal one.
