You took the words right out of my mouth. I have communicated with a prolific provider who stated nothing about not welcoming Asian clients in his ad. When I contacted him we conversed for a bit and he asked about what I looked like because he wanted to make sure he’d recognize the correct person who’d show up at his door. Once I described myself he simply said I’d have a better time with someone else. it wasn’t rude, but it did not make me feel good. I blamed myself for reaching out to him, for not knowing my place and asking for the impossible. This was before I started researching about providers and it turned out that his preference was quite well known.
This has happened to me more than a few times with different providers.
Some providers do so well that they don’t welcome all types of clients and although it does pose a question about professionalism as @Jamie21 eloquently said, I respect their discretion. I just hope that they are honest and straightforward about it upfront in their ad so nobody has to waste their time. I understand that having stuff like that on an ad is bad for business, but if they’re going to have a preference they need to accept the caveats.
Personally, if I were confident about my appearance and did not mind rejection after communicating with someone, I would have stayed on hookup apps and not considered hiring someone to make me feel special.
