I hear what the Sisterhood is saying, Dani; but last year, I saw a WG who's a "Featured Escort" on AW from time to time.
During the course of the session, I mentioned "Paying for Pleasure", the book by Teela Sanders, the Leeds University sociologist who had interviewed a sample of punters [including me] to get our take on the scene. Because I'd been interviewed for the book, I bought it and mentioned this to the WG. She asked to borrow it, and I left it with her on my next appointment. Which turned out to be my last with her, because she ignored any request for future meetings.
If I want to, I can always get another copy of the book. And as for the "Featured WG", when she didn't reply I just thought it's a "Buyers' market" and moved on to a different and, imo, better WG.
Very short-sighted of her, imo.
