Actually, the more I read these links the more I'm disgusted by the idea of any woman considering this industry by choice.
Most women don't know what they are getting into though. Even the OP has shown her naivety when she mentioned that she was interested in being an escort, but not willing to do anal, when it just doesn't work like that. But the industry uses all sorts of tricks to lure women into it and break past their boundaries.
The brothel where I worked would put out ads out every week seeking a "Lingerie Waitress" or "Sensual Masseuse - No sex required!!", and when girls turned up for an interview the manager would say that the masseuse or waitress job had been filled that morning - but the owner also had an escort agency and perhaps the girl would be willing to try that instead?
The manager used to work as a escort herself, and knew all the right things to say to make the girls interested and comfortable with the idea. Before you know it the girl had agreed to her first trial shift. As the booker it was my job to make sure the new girl had abundant bookings on her first night with the best clients. Then she would go home thinking "Wow! All this money for just 6 hours work!" and then she'd commit to a month of shifts. But it was unlikely she'd ever make as much money as her first night, agencies and brothels have as many girls on shift as possible, so the punters have choice, but it means that each girl makes less money overall. By the time girls realise this however, they are usually knee-deep in the industry and once you're "in" it is so difficult to leave, for various reasons I won't go into because I know I've started to rant on this thread.
I could write so much about the industry and how it works though. Pimps, brothel owners, managers, drivers -- they are fucking scum. They rely on single mothers struggling to cope, battered wives fleeing abusive relationships, immigrants, naive students, and other desperate women.
Belle De Jour, Pretty Woman, and all the other cultural crap is propaganda. It really is. Don't believe it.
