Following on somewhat from @StopStartStop
These are not my opinions, I'm literally quoting a podcast I saw...
The guy said that men and women are not equal because they see the world differently and want different things. Women are attracted to men who are characteristically 'dominant', i.e., tall, strong, powerful, assertive, financially successful, confident etc... men are attracted to women who are beautiful, meek and "not difficult".
He said that strong successful men attract many women, and being sexually promiscuous is a desire for men, and in turn makes him more attractive to other women because if other women want him, he must be good. Women should just accept this from a successful man.
He said that men want something different from women. Men don't care about what a woman makes, her success, her power, popularity or ambition. A man just cares that she is 'his'. This is why men lust over the OnlyFans girls, but would never marry them. The worst thing that can happen to a woman is to be raped (his words), but for a man, it is to find out a child isn't his.
I find all of the above massively sexist, but from those comments, it answers your question. To be attractive to men, a woman has to be chaste and loyal because signs of the opposite risk a guy's worst nightmare (a child that isn't his). Successful men get lots of sex, so to boast about sex is to 'demonstrate success'???
As I said, not my views, but another perspective?
