I'm not reading three pages of this, but I wanted to say something to the original poster.
It is your body, see who you want. This is a HUGE thing in the US and the policy is called "NBA" which is "No Blacks Allowed". This is no more common in southern states than northern, however it is more public and accepted in the south. The girls in the north just don't reply to you or won't open the door once they find out you're black. Harsh.
ANYWAY.
The policy is called NBA but usually includes Asians and "Middle Eastern descent" as well. The line "I care not about what you are, I care about what you're not" is one I seem to recall from somewhere. It means White's Only honestly, but that sounds a lot worse than NBA.
Here's my point Ms Erica. You are leasing yourself out as a service. You have the right to choose who you do and do not lease yourself out to. Some of the most successful providers have policies like this and do just fine. Your reasons are your own, whether they're racist or not is not for any of us to judge. And honestly, I wouldn't have even revealed as much as you did on here. I would have stated that the reason is not race it's discretion and left it at that. It is NO ONE'S business who or why you choose to fuck or not fuck someone. Not ever. Just because you are a sex worker does not entitle PERB, ERSLIST, or anyone else in this world to pry into why you do or do not let someone into your pussy.
