wow.I'm a [I guess you could say "white-acting"]black girl and I basically have the same problem as the OP.And I like thin asian guys with long hair,but I can never find any!!!!!
[that aren't MEGA weird at that...]
hmm..maybe you should just look for otaku's...or look out for a few of the more quiet girls.just know that there are quite a few of us that don't act like that ^^
and that you'll probably find the right girl
