It happens over in India quite a bit.
Some of the prossies over here only seem to punt with reasonable looking guys.
I put a friend in contact with a prossie who I used to fuck on a semi regular basis, and she told him she wasnt interested.
I asked the girl why and she explained it to me that with some of them, they are reluctant prossies, they like the money (one of the girls I fuck charges 3 x the average monthly salary for one 'pop'), but they also know the cultural view on what they are doing, so they can convince themselves its a 'mutual' thing if the guy is reasonable looking.
