Ask two questions: Does it benefit women? Does it benefit men?

You get positive points for the first one, negative points for the second. If your score is negative, congratulations, it's sexist. Games with attractive women appeal to men but don't benefit women, so they're bad. Onlyfans whores are a massive wealth transferal system from men to women, so that benefit to women outweighs the benefit to men, so they're good.

The line between "objectification" and "empowering" is simply whether there's a woman benefiting from it.
