Nice thread. im also a newbie.
Is the sex guaranteed, or do you have to convince them? or what?
In fact, don't bring up sex at all.
At all. And don't get your wallet and start counting out 20s. Put it in an envelope and lay it on a counter or whatever.
She will fear you have a badge. She will fear entrapment. (And frankly, so should you. That's why some services require identity checks. and so on.) So yes, treat it like a date. There used to be a review board that offered tips and news for "hobbyists." There are lots of pitfalls, such as an upcharge, substitutes, fakes. It's definitely YMMV and buyer beware.
I dipped my toes in that water twice, and quickly decided that the cost would keep me in beer and tips at my regular strip club for, oh . . . a year?
