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.
Conceptually I have no problem with it, but in practice a lot of people feel like they “should” or “have to” become sex workers out of desperation for money. That can seriously ruin your life. Work under capitalism is inherently unethical, but sex work especially so.
