Yes. They sexually fantasise over them because of the stereotypes which include a large gonad, and aggressive demeanour in the bedroom.
Additionally, they use them as a method of rebellion.
If a girl wants to upset her parents (in particular her daddy), she will bang a black guy. Whether they are aware or not.
Some girls, are used to having Jack's and Ben's that she's curious to know what a black guy is like for a change.
Some girls have been with a black guy and realised there's no going back. Nothing can compare.
Or, some girls simply don't care what race a guy is because she is more intelligent than that. She is attracted to anyone who is attractive with the ideal personality. Notice I said ideal personality not 'nice' personality. Because no girl likes a nice guy.
There we go.
