Talk to some college age males...or females for that matter. It isn’t unusual for one male to be servicing/seeing, whatever euphemism you like, several young ladies. Tinder and similar apps have guaranteed this.
I can take similar anecdotal evidence from people I know. I've known several women who dated successful men. None of them would date a guy who was also seeing other women.
Does that mean NO women are slutty enough to go to male whores? No, there are always exceptions in any population.
