Not sure where in the world you are, but there is at least one in New York City who I can confirm is real because I have spoken to him on Grindr.

And a few I'm unable to confirm but are out there!

I'll add him to the list! I'll note that he's a masseur as opposed to a full-blown escort... he is a really handsome guy, beautiful smile. Thanks for the info!
No experience, but he's near me on Grindr when I'm at work in Murray Hill. I actually walked by him on the sidewalk on Friday, recognized him from his profile there - very handsome, average height for intel's sake.
I happen to know him personally and he is truly one of the most down to earth people. Very rough around the edges, but he's good people and always in phenomenal shape.
