Why do guys slut-shame?

Anonymous
Yes guys do slut-shame for some reason, it isn’t just women. I understand why women slut-shame each other (it’s because women often get jealous of one another, and the amount of sex one gets is no exception) (keep in mind though that understand =/= agree), but I don’t understand why men do it.

Unless she cheated on you and gave you an STD in the process, why do you care? How does a random woman’s promiscuity affect you?

It just seems like a waste of energy slut-shaming people whose choices don’t negatively impact my life, that’s why I don’t care about other people’s sex lives.
