Edit to add my opinion so I’m not just replying “I agree” to 90% of comments. I think it should be legal, properly regulated, taxed and viewed as a profession. I haven’t personally engaged in it but I have no moral objection to it. I do hate the common sentiment that it was the individual’s “only option” though.
I don’t even think buying should be criminalised. It just makes it harder for sex workers to find clients for no reason.
