Most women are slutty bc of insecurity and people-pleasing tendencies and a desire to fit in and a desire to be in relationship w a guy they find attractive, w/o expecting him to earn it. Once all that has been healed (and it is totally possible to heal) the sluttiness just disappears.
And yeah, I know there are unusual women out there who are slutty for the love of sex, and that’s cool. But that’s unusual and social rules and expectations can’t be calibrated to the minority. That doesn’t work.
