hahaha! Sorry, I'm not laughing AT you, really... that's just funny.
Well, not all of them do, for one thing. It depends on the guy. And a lotta guys are into *different* kinda looks too---not just one. He might like a girl with a big ol' a$$... and then the next week he might like a girl with NO a$$ at all.
Personally, my bf for 7 months now is black and he says he perfers things "medium"... not too big, not too small. Lol... which also conveniently happens to be what I am: medium thighs, a$$, and tatas... so I dunno if I should believe him or not. (Just kidding, I totally believe him. He's a sweetheart.)
But to get back to your question, if a guy isn't into you just because of that... maybe you should just find somebody else. And don't concern yourself about what color he is; just find someone who likes you for you. He could be from any background.
But to agree w/a poster above me, my bf likes to smack it too... and I like it when he does. So thank goodness I've got enough for that grabbin and spankin stuff. =P LOL
