Never cared. I've dated white girls, black girls, asian girls... physically the differences are not that important to me.
Where it does make a difference sometimes is culturally, but culture isn't always related to race, or attraction. For instance one Asian girl that I dated was brought up in traditional Asian culture and had strong values pertaining to that culture, which meant that I didn't have a lot in common with her ideologically, another one I had a stronger relationship with was brought up in Western society and had a fairly different value system, much closer to my own. Those sorts of things can definitely make a difference to the viability of a relationship, but they don't make a difference to me on a pure attraction level.
