No beef. Just being very technical I guess. But I'm sure prostitution wasn't first. If you think about it, something would have had to be created in order for someone to say "hey, I want that and I'll have sex with you for it." Whatever that is that was created was probably something of use and made for something else. Besides, back in the cave men days, I doubt many men asked to have sex with a woman. It was probably some sort of ritual and whatever man won got the female. I'm sure when people could speak and form villages prostitution wasn't far behind. Whatever.
Maybe not. Maybe they were a bunch of cucks. "Hey Grok, if I give you my woman, would you let me watch?"
