I’m not against those who work for sex, but the idea to earn for a living doesn’t seem nice. IMO, sex should be for 2 people (or more for others who prefer polyamory) who wants to be intimate/romantic with each other. My point is money should not be the purpose.
Legalize it, tax it, regulate it like any other job.
I’d not buy any, even when single.
I would consider selling before a lot of other jobs. Depends on the money really. Not much of a market for straight, average looking, men in their 30s however.
