A good question.
I don’t think I need to express that love and sex are not mutually exclusive.
Men are richer, even today. Some women are willing to chase that to their own ends. There are girls I personally know who have sugar daddies. If I was on that level of material thinking, I could’ve been myself. The only reason a man would feel disdain for that, in essentially what random next persons choose to pursue, is bc what you’re pursuing (sex with hot women) and what they’re pursuing (riches) puts you at a serious disadvantage from the jump on what you want, so you neg them, meanwhile no one blames a guy for not pursuing the male equivalent of this (fugly women).
That’s my reasoning for being convinced by he term gold-digging being made up by bitter men. Women certainly don’t call each other this.
