If you have coin, I am sure they are all interested.

I would think that if you have the money that most providers would be down with that. Although I'm always a little shocked when I see a provider that says no DATY allowed. I assume for some those chicks, they consider that to be too intimate or worried about dirty mouths or whatnot.
 I typically don't perform DATY because I think about all the dicks that've been inside of her. Sometimes I might make an exception if a woman is extremely hot or if she's able to squirt but typically I don't perform that or a pro.
