That sounds exactly like an escort with a fancy app.
Plus maybe you don’t need an escort if you are a match with someone else looking for the same thing as you.
strip clubs I imagine. They can't legally say they have escorts, but it's an entire scene. Like any other tribal knowledge, you need to know the edge cases and know the right people. And/or be rich. You can't just google this kinda stuff, you gotta get out to your town and dig (well... you kind of can. But you don't want to take the risk asking for certain Craigslist ads on this stuff).
Or you can go to Vegas where prostitution isn't illegal.
