I tend to like longer bookings so unlike you I always ask SPs if they are comfortable with black guys. I appreciate not everyone is a swirler or they only like to swirl with certain races. I would feel awkward as fuck if an SP opened the door and reacted strangely because she was expecting a white dude. There's also some black SPs that don't want to see black guys too. I think on AW young white Brazilians and Asians refuse to see blacks the most. There are racist SPs that do see black guys because they put money over everything. So it's hard to determine a SP's political views.
As for May, I don't think she is racist. She told me she has dated a Jamaican man before and likes BBC vids

. I emailed her a couple times about her availability and her services but didn't get a response. On a third try she did respond. She explained that her work life balance wasn't great at the moment and said that she will be redoing her profile. You did mention she was polite and I found her very polite too. I told her it would be better to put that she prefers to see black "Western" men if her only problem is a cultural issue and not a racial one. She has no problem with seeing me so she will be staying on my HL.
