Feel free to tar and feather me with accusations of stereotyping.
I would be extremely cautious about the imported black chicks in most of Asia. While in the U.S. I've had some absolutely wonderful, mind-blowing experiences with black chicks; these were all girls who were born and raised in the U.S. and were part of the U.S. culture. You can also find this kind of quality attitude with black chick born and raised in Europe.
But black chicks fresh off the boat from North Africa anywhere in the world tend to have (IMHO) a very mercenary attitude that would just as soon slip you a rophie as fuck you and take your kidneys too.
O.K., so maybe that's a bit over the top . . .
But the point is this: it's not because they're black, but rather the place and culture they come from. We all know the very high service attitudes that Asian born chicks exhibit in this business. It's spectacular and literally a gift to all mankind. Well, other cultures aren't so progressive in their service/prostitution attitudes and some cultures are even the exact opposite.
That's just my opinion and I am more than willing to be corrected on the matter.
