I just dont see it at all in that way! The fact that an escort advertises herself in effect means that she is issuing an invitation anyway to the general public and unless there is a major problem,she is likely to proceed with a booking with whoever turns up at the door. Now if I were her, I would far prefer to have a greater say in who turns up.
Some time ago I received a pm, out of the blue, from one of the most beautiful and successful ladies on this site. I am sure she had no great reason to contact me other than she had formed the view that I was generally the type of client that suited her. I thought more of her, not less of her -- there was nothing 'personal ' in her approach -- it was just good business and I respect her fully for that.
