Conventional wisdom suggests promiscuous men are revered as "studs" but promiscuous women are degraded as "sluts". Is this really true though? I don't think so.

Common negative attitudes towards promiscuous women are best characterized as "disgust", people think what they're doing is in poor taste and it feels "icky" to them. But few would characterize them as malicious or accuse them of harming others with their actions.

Whereas common negative attitudes towards promiscuous men are much harsher, and are better characterized as "condemnation". Women are heartbroken when promiscuous men don't give them the commitment they want, and as a result promiscuous men are labelled as being malicious people("he's an asshole", "he treats women like objects and discards us after he's done", "he exploits and uses us for our bodies", etc). Even when they don't lie to women, they are attacked and criticized regardless because women feel entitled to commitment and they don't provide that. They are viewed as if they have wronged women by not having relationships with them.

TL;DR promiscuous men get accused of doing evil, promiscuous women do not.
