Yes, there is but it is not clear cut nor is it the same for all white women. First of all, in some sectors of our society it is still taboo and forbidden fruit to even have sex with a black man. My wife is an example of that. She was brought up in the deep south in a deeply racist family. The thing is she is VERY attracted to black men and them to her. She loves making love to them and being with them. She has kept this a secret from her family, they would not understand. She had a few black boyfriends in secret when she was in high school but didn't really get into dating them until she went away to college in New England. She had many black lovers and was known on campus as the girl who loves black men. During that time she also found out she was very submissive to them. It's hard for her to explain but it does come down to the attitude of her family that black men are somehow sub-human. This added to the excitement of fucking them and she found herself agreeing to be shared with their friends and other black men they knew. It appeared there was money exchanged at times.
Fast forward to now. Seeing as she kept this a secret from her family and hometown friends, she seemed to keep her relationships short with her black boyfriend, nothing long term and she ended up marrying me, a VERY white guy! I didn't know about her sexual adventures with black men until several years into our marriage. I was intrigued and that is when I started sharing her with black men. I found out just how submissive she was to them and she was so eager to please that nothing was off limits. She did stuff for them she never did for me. It has included her fucking other men for money, money to her black lovers not her. It's complicated. I have a theory that she feels guilt and uses her body to make up for the things her ancestors did to them as slave owners and the fact that her grandfather was a member if the Klan. Racism is at the root of her obsession because if goes beyond mere attraction. I don't know if this make sense. I hope I haven't offended anyone!
