I'm sorry but I can't totally agree with you @MeowDoku. I know that it feels very uncomfortable to think that consent to having sex is a buyable - figuratively speaking - commodity, and it surely isn't found in young ladies hijacked from abroad, and it probably only rarely exists in Street walkers, especially those that are controlled by pimps.
However, there are many 'higher' class sex workers who can have a lot of control - or even - total control, of how, when, and with whom they agree to have sex. I know this through an educational project I took part in a few years ago, where I was able - after a lot of negotiating with either the sex workers themselves, or with their managers/husband/mothers etc, to interview some female 'escort' sex workers. Most of the latter get to 'visit' their clients in their 4* hotel rooms, which was much more comfortable and hygenic, than in the back of a car, or up against a wall in a dark alleyway, etc, and a lot less dangerous.
I think that 100% of the escorts that I was able to interview were all female adults, some began their lucrative work while they were still at University, a couple of them started selling thrir bodieds for sex from as early as their late teens - which did, and does concern me, were they being coerced into renting out their bodies from such a young age, even though the conditions in which they had their liasons were more attractive, and usually more comfortable, than those of the street workers etc?
I don't think that I can accept that the teenage, possibly/probably groomed young women, were capable of choosing for themselves. But the slightly older escorts, in, say, their late twenties and their thirties, were eventually able to convince me that they most certainly did, and do, consent to being paid for having sex with a male client. Those women were all articulate, and had very friendly demeanors. Of course, they could all have been extremely good actors, but they really had no reason that I could think of, to lie to me. My study was not going to be published to the genaral public, or even made available to any managers or pimps that they might have had.
