For me, race has nothing to do with attraction .
I have some criteria about lust, crush, male or female beauty, and race or skin color doesn't belong to them.
Its a "chemical" process : mixing of sex pheromones, of remaining of old images combined with pleasant feelings, depending of your mood in the moment. Sometimes, foreign race is not my taste and there is no attraction. Sometimes, I need a change and my first feelings are positive, just because the race.
I don't have a lot of experiences myself, but I had a daughter who was very fond of other "races". She brought home (but only one after the other and never for a long time ! ) Chinese, Hispanics, Gypsies, Afro-Americans, Beauties from Martinique, and sometimes even Swiss hippies ! They were always well adapted to the situation and belonged to the family as long as my daughter was ready to accept them. Sometimes we had at the beginning problems to be accustomed with the first names, which changed so often....Funny times and funny/happy life .
