Face it: Frequently, a stripper or escort by herself will have more problems than everyone else you know combined, and, just about as frequently, she won't mind sharing them with you at all, thank you very much.
Sometimes, the real name comes out because she's careless. Sometimes, it's because she doesn't really care if any and everyone knows. But some other times, it's because she trusts you.
I don't mind being let into a provider's life, but, if she's going to tell me how screwed up her life is, I need to be able to reciprocate.
