I don't know, but I know I've dated Japanese girls who shave their pubes clean off and those who don't, and to tell you the truth I for some reason prefer the latter on a Japanese girl. It just does it for me. I kinda like running my hands through them while I'm going down on her. It's usually so warm and soft, like a teddy bear or a kitty cat. It's a huge turn-on.
Not that kitty cats are turn-ons, but you get my drift.
But yeah, the shaved girl was really aggressive and mean. The others were usually nice to me.
I would say more or less all girls are the same, as far as nationality goes, at least in the sense that they're all different and you never know what you're getting into. Hell, we all watch the same moves and listen to the same music, we more or less share a popular culture. Our ideals and mores are more similar than they've ever been before.
But yeah, Japanese girls with thick bushes do it for me. Mmm...I miss it.
