"Paying for sex is just a different way of exerting the same control, since the person with the money calls the shots."
I ask again, as I asked lower down. How does this differ from paying for any other service in that the person paying calls the shots? Except that sometimes the person offering the service and charging the fee (especially in a sellers market) can also 'call the shots'. In a mutual contract. Plenty of escorts etc define thier own terms and are clear about what they will and will not do, what is required of the client etc.
I was at university with someone who made money through selling sex. She was studying law (and is now successful in her chosen branch of work, I see her quoted or cited as an expert in the newspaper sometimes). She had made a decision to separate herself from the prevailing moral currency attached to sex (that it was too special to sell / too demeaning a job / or made her a victim of oppression) and to sell the service of sex on her terms. We all did different jobs to see us through our student years, things we don't do now (mine was washing up on the night shift in a hotel), she chose sex.
Women pay for sex. I don't know how many, but there is a business in male escorts. Possibly more women would pay for sex if it wasn't socially such a taboo for women and they didn't feel embarrassed or self conscious about it. Women pay for sex in other ways - holidays to places where they can meet a local 'boyfriend'. So how can the paying for sex always be about male oppression of women?
