I am 100% on board with people doing with their body whatever they want. Restricting that is just ridiculous.
But that also necessarily means, they can decide to do immoral things with their body, which I do not need to be a fan of. And that's where I'm still somewhat undecided on how to think of the whole sex work industry.
As you say, to some degree, it is simply mental care for those customers. I do think, the offering should exist.
But it's also all too easy for it to become extremely exploitative.
I'm thinking, in some far-off, progressive future (not sure, if we get there before work stops really being a thing), there would be self-help groups or simply therapy offerings, for those who spend their life earnings on getting sex work done.
