"Clean and dirty are industry words"
No, they're not, they are words the industry (which is based on misogyny) has adopted from the old, old old canon of words used to split women into whores or madonnas and you accept that division Sugar, because you got to be placed in the madonna category so you could sneer at the women in the whore category. It's a self-defence mechanism by women, to place themselves in the madonna category because they know that at any time the people with the real power - the men - divide them out into those categories.
And I hate to break it to you, but the men who buy the sexual services you sold, don't make the distinction - as far as they are concerned, you're all whores, whether you do extra or not. Because madonnas don't work in the sex industry. Just by being there, as far as the skanky men who frequent lap dancing clubs are concerned, you're a whore, whether they're allowed to touch you or not.
Quite often for punters, the thrill, the real hard-on, isn't the fucking or the touching or the watching - it's the handing of the money over - the symbolic feeling that these pathetic wretches have, of owning the women for that short amount of time. Doesn't matter what she does for it - chat, fuck, dance - it's the fact that he's bought that service and she does it for him that gives him the boner.
I find it very telling that you feel the need to lash out at posters who question your version of the sex industry and to use such horrible contemptuous, stigmatising language about the women the hierarchy has placed in the dirty whore category. You know damned well that other people use the same language about you, because we live in a society steeped with misogyny and women desperate to place themselves in the madonna category will always find a group of women beneath them, who they can place in the whore category. Doubtless the "dirty dancers" looked down on brothel whores; the brothel whores can look down on street walkers; the women who look down on you are looked down on by other women who wear different clothes from them; and meanwhile, men rule the world.
