Do guys not want to date black women?

guys get nervous around girls they like, and no since the 60's I've had male friends who are white (I'm native american) and they will only go out with black girls but they say that black girls won't go out with them because back then their families were not accepting of interracial marriages, and only the black guys had the guts to go against their parents, but they found some who'd go out, just not the really dark one that they really liked (I don't understand the difference from within a race, but well few of us so...not much to pick from without going out of our race no big deal.)
