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.
Well that is a good point, and an important clarification.
I do object a bit about the 'humans being animals’part, that seems to undersell the soulfulness of most animals (but that’s a bit off topic).
If a person were entirely filled with enjoyment of sexual acts and in full control over whomever they rendered their professional pleasure to would that scenario be more or less soul destroying than, say, a standard workman grinding a job he doesn’t like for things (s)he finds most important, like family?
