to be completely scientific, and you can believe it or not, it really goes to the fact that men want to spread their genes to as many women as possible, if not as far away from where they started as possible.
This is a prime example, as in this country (or this part of the world) there are lots of pale white european originated males (yes and females), that really like the dark skinned, and in this case, Asian women. Theyre different in looks, culture, and whatever from them; therefore, on the primal level, "theyre hot".
Then there are the other guys that just want the jdm gf to match the car
we sould start a new thread for this...
