I've actually read through a couple of books about this. Maybe read one if you want. I did that and have skimmed a couple of others. But they're really nothing special. Things like how tired the girls get of the guys, and how a lot of times they don't even notice who they're dancing for. Things like how all dancers have their limits that they have to find to be comfortable. Things like commercializing sex a lot of times leads to the girl enjoying sex less. I've never really seen anything earth-shattering in these books. Maybe if you haven't seen one before, it'll spell out a couple of things you haven't thought of before, but nothing that you look at and figure you'd never would have imagined that. There's just really not that much mystery there. Did anything in the article that describes the book above surprise anybody? The book will be more of the same.
