Maybe I'm posting to the ether because this thread is a little dated.
That may be a good thing though. Confessions first. I'm a man. Technically I think that disbars me from being a feminist (at least according to some of the posters on the feminism section of MN). Even if it doesn't, I'm not sure my daughter would describe me as one anyway. And for full disclosure, nor am I a punter.
But I do believe in equality and respect. And that extends to whatever someone chooses to do in life, so long as it doesn't hurt someone else, whether they are a teacher, a social worker, a banker, a sex worker, or a politician. They all deserve respect. Even George Osborne.
I actually couldn't find your earlier post, but you gave a flavour of the responses here. I tend to think the comments generally in the relationship section of MN can be very harsh, so I can imagine how posters might have treated you.
If you chose freely to do what you do, then I for one have nothing but respect for you. There is nothing to be ashamed of and no one has the right to tell you otherwise. Plenty of people do jobs that many would not want or be able to do, whether that is trading derivatives, playing professional football, working in a sewer or providing sexual services. That doesn't invalidate any of those services. They're just jobs. And it certainly doesn't entitle people to criticise you. I'm sure you know all that, but I hope it helps to know that not everyone thinks less of you.
If you need validation, watch The Sessions.
So keep doing what you do if you are happy in yourself with it, and you take precautions to stay safe.
At the very least, you can rest assured that on this feminist support thread, with a man writing in support of paid sex, you are unlikely to be the one getting flamed.
