We all have preferences and likes. Those features that attract us to others. what about them excites and interst us. Since Fetish is liking something that is outside the social norm them yes racial or cross racial attraction can be a fetish. Take hair color as a simple example. Most men look at a woman and have some reaction based on the color and style of a womans hair. Some men are attracted to 'exotic' woman. A white male might find asians attractive this way. Or someone that fits their erotice profile like a dark haired gypsie girl. i think white men find black women attractive in the same way. The relationships get a little more confused and hard to sustain because of the baggage assiciated with whites enslaving blacks in the past.
The idea of having control over another is a powerful thing. To be controlled by someonbe can be equally as powerful. So if having a white male exercise that control over you makes your knees weak and your panties wet then you obviously KNOW what you like and want. I was a psych major and still think its less important to know your desires and enjoy them than to spend to much time analizing them.
