On the podcast The Mental Illness Happy Hour a guest was a sex worker who considered herself a sex therapist and made it sound like while she did do it for money she truly believed she was helping people who desperately needed contact and help, I don't think it would necessarily happen like that under some sort of communist utopia but as long as jobs exist and people who need therapy, sex and otherwise, exist I'd bet there will be people who'd do it. Hell, there are people who will throw people a pity fuck for free. But please, I do not want to be in the discourse lol.
