No one has a fetish for white cocks. It's the default in society. Every woman wants a white beta provider once they hit the wall past 30. White men are generally docile, predictable, and boring. There is nothing exciting, taboo, or arousing about letting little timmy dribble his tiny clitty in your pussy so you can be supported financially.

BBC is a real fetish because it's so transgressive and taboo. Black men are seen as animalistic, wild, and unpredictable by society. Women feel a real sense of danger and excitement when in the presence of a black man. This turns them on and heightens their sense of sexual pleasure. That's why BBC has been a thing ever since African slaves started coming to America. It's a natural reaction that women have when faced with a strong, virile, black man.
