If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
I don't have a lot to add except to say, I can't think of a single reason why not to do it. Which makes me just a bit confused, because it's unlikely that this is the only time that society has generated a widespread taboo against a thing for literally no reason.
The reason in the past was probably disease and/or unintended pregnancy, and both of those can be fixed now. Also concerns about making sure women wouldn't cheat on their husbands and leave them raising someone else's kid, I think. The third reason, which is still applicable today, is that hiring a sex worker signals "can't get sex without paying, therefore undesirable" but that's probably not too big of a deal.
