Nicely said!!Let's be honest here.
If people find sex work shameful, it's because they find no-strings-sex shameful.
It's because they think sex is something that should only happen between people in a relationship, or at least between two people who have just met and are exploring something that might become a relationship.
Reducing sex to a transaction is seen as the opposite of a relationship - too clear-eyed and honest, perhaps, when our culture prefers to romanticise these things, to suggest that there are never any motives beyond twue wuv for women to have sex. (Nobody ever bothers to suggest men's motives are so pure. Funny that.)
Never sex in return for a nice meal or some drinks, or sex for a bed for the night. Never sex for the sake of not being alone, or because it's expected in an ongoing relationship, even if you don't feel like it right then. Never sex because you're a wife and it's part of the house and land package.
"Nice" women have been selling themselves since the dawn of time. They just monetised it differently and scrabbled for something to give themselves the moral high ground. So other women - who were involved in more straightforward transactions - were called prostitutes or whores, some got to be mistresses, or courtesans, and others wives.
Men, of course, were terrified of these straightforward transactions, because they were free of the control that they had over their wives. "Hand over the money, do the sex, walk away" gave sex workers a power wives and mistresses never had. So those women had to be reviled.
And here we are today, liberated from shame about sex and our bodies, and this crap is still being peddled. "Respect" for my body? Really? I find it really offensive that anyone should suggest another woman lacks respect for her self or her body because she chooses to use it to support herself. Some sex workers may not, some will. Being a sex worker doesn't automatically equate to one frame of mind, one background, one fate.
The shame lies with social structures that perpetuate this rubbish and do their utmost to drive it underground, making it an unsafe, sleazy profession BECAUSE of the shame heaped on these women (and men). People trafficking, drug use, STDs and the like - these are social problems that need to be tackled outside of the framework of "prostitution! egad!" and would be a hell of a lot easier to minimise if sex workers could admit what they do and admit that it's out of free choice, rather than compulsion.
Same goes for p.or.n, actually. Let's stop jumping up and down about the shame, and how awful and immoral it is, and concentrate on tackling the risk factors and misogyny and criminal acts that infiltrate an industry that is sleazy and underground because so many moral majority types insist on keeping it so.
