I read that piece a while ago and thought then, as I do now, that it's a pile of shit.
I do loads of things with WGs that I haven't done with girlfriends. I do them because girlfriends haven't wanted to and because I find them fun in the extreme. It must be lovely to live a delusion that all men are arsehole women haters, absolving yourself of any responsibility for the decisions you make, things you don't like, regrets you might have etc, in the process.
I'm a grown up making decisions about what I'd like to do with other grown ups, of our own free will, harming neither ourselves nor anyone else in the process. Bad people do bad things to vulnerable people, that's the problem, not prostitution.
