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 think it should be legalized. The only thing wrong with sex outside of procreation is absolutely nothing. I have a hunch it would help with a lot of social ills out there. Why, in most depictions of the old west, you could go to town and get a prostitute. Eventually, powerful people with sexual hang-ups and twisted morals restricted the activity and pushed it underground where it’s dirty and dangerous.
