I don't guess it needs my approval but as long as there is a demand for the service it will happen.

Like you, I just like everyone to get sex for sex, that's how I've always done it, but that's a very recent outlook, it was very gatekept before and women generally were trading sex for something, and men were generally trading something for it. I remember being in high school and the only categories were girlfriend, slut, or just don't have sex, it was so fraught.

I expect there may always be a marketplace. And certainly don't hold any sort of bad feelings towards those trying to market themselves, if you can make a living at it, great.

Went to barber school with a lady who was doing job retraining after getting busted for prostitution. She said she really had enjoyed it, had few clients, all regulars, worked out of her home, made a good living. Wasn't bothering anyone until apparently someone noticed and was bothered.
