I would not say that they are greek providers but I have a regular that will everytime she is on her period. I like it and sometimes I time it. : ) She will complain a little afterwords if I am too fast, deep or take too long. But we kiss and make up...Lately though, I have been looking for it with older pros and I have found that its just a matter of asking and there is no upcharge, meaning it just goes there. Seems to me some of the older providers are pretty much experienced and open to it. Do they like it? I think they take some pride in it but who knows?
