[btw...I think that this is completely irrelevant practically for most of you, as you are in the UK...but just a from a different note...]
Most US escorts won't see black men...or...maybe not true...will not see black men who do not work in office buildings in suits...because of experiences in which a black client has either attempt to become "management" or attempt to underpay.
I think in the US race is so ingrained in culture. I just don't get/cannot relate to/connect with African American culture.
I tried to work at a strip club that predominantly had black clients. I quit after a week... it just didn't work. I couldn't read class (aka who had money); I had no idea how to talk to/approach most of the customers. My approached didn't work. My dancing didn't work. I just didn't know how to read or take control of anything.
By the last day, I was basically just approaching the guys who dressed and acted white and the minority of white/Asian/Hispanic customers in the club.
My mom's fam is WASPY. My dad's family is middle eastern blue-collar Christian (and very misogynistic...just went to a wedding last weekend...re the Asian thread...I understand what you mean... I think in certain cultures it is a very different way of playing into male fantasy and at the same time taking and maintaining control. I think if you went and lived with a ME or Asian family for a year, you'd realize that it's not men-power/female-disempowered...it's just completely different)
So I take white collar anyone, and hispanic/asian/indian/middle-eastern white not-white collar.
I think it's for me, and maybe for other people, knowing that my range of work personas will click with a client/an understanding of what they want/an ability to relate?
Different cultures have different interaction styles and different conceptions of gender roles (which I don't necessarily think translates into power or not power, but just different ways of asserting power)...and all of this is magnified in sexuality...
I really do believe that the type of "attraction" to clients in any type of sex work involves an ability to relate/understand the client and feel in control, all of which takes an amount of cultural fluency.
Cultural literacy is a good thing to want to learn, but certainly not in a situation like this!
