What I've found interesting is that the industry that will do just about anything for the right price overwhelmingly has an exception by most of its practitioners -- no black men under any circumstances.
By that I'm referring to the oldest industry. And yes, even black prostitutes very often have this rule. However many will make exceptions so long as when they speak to the john on the phone, his voice timber/accent doesn't sound black, as that person typically hasn't been exposed to black culture, which is the main problem in their eyes, and not the skin color.
Here's the most important part:
The strongest proof of this I can offer you is that while most white girls can be persuaded to see a black client if he is well-spoken and/or lives in an affluent neighborhood or stays in an expensive hotel, many black escorts will not see a black man under any circumstances; in the words of Tina (a simply gorgeous black girl who was Flavor of the Month for quite a while), “They’re too cheap, too rough and too full of themselves.”
Obviously, this isn’t true of all black men; I had several black regulars over the years (including a salesman who saw me about once a week for quite a while), and the only complaint I ever had about any of them was that one poor guy tried so hard to make himself agreeable to me that his skin always smelled and tasted like soap! But what about the rest of them? I’m afraid I have to agree with Tina; the majority do tend to be exactly as she described, and I think the reason they are that way has to do with their subculture. For reasons others are more qualified to analyze than I, the typical male role model for young black men is exaggeratedly masculine, physical rather than intellectual and tends toward violence; he is a sports star, a “gangsta” or a “bad-ass” action hero. And one doesn’t need to be a sociologist to recognize that this self-inflicted stereotype is related to a deep current of misogyny in the black community;
That's pretty much all that needs to be said. Unfortunately, if you try to talk openly about this, you're instantly labeled a racist, which is pretty much THE word to use these days if you want to shut somebody up, especially if that person is white, because once that accusation is thrown at somebody, it's basically impossible to prove otherwise.
