It's more socially acceptable to slut-shame men than women

"He's a fuckboy"

"He sleeps around because he's a misogynist who views women as sexual conquests"

"Real men aren't scared of relationships"

All these sentiments and similar are common and some variation of shaming men for sleeping around and/or not wanting committed relationships. None of these would attract criticism from mainstream media or society, result in social ostracization, or professional consequences, unlike men who vocally criticize female promiscuity.

Broadly, women feel entitled to criticize men for sleeping around and not wanting monogamous relationships, and most people regardless of sex don't find these criticisms objectionable.

Of courses, many women will try to dishonestly reframe the debate by claiming things like "fuckboys are dishonest" when in reality the label gets applied to all promiscuous men regardless of honesty. And they define "dishonesty" overly broadly to include things like women assuming an interest in exclusivity just because men never indicated otherwise.
