What an awful view of women. Must be a serial killer.
Are there some women who are narcissistic sluts? Yes. There are some men who are narcissistic sluts, too. I'll let you in on a secret about the promiscuous women: very few of them like having serial relationships or one-night stands. Many or most want love, not serial sex with strangers. Sex with a strange man who doesn't know your body isn't that great anyway.
Such a woman doesn't know how to say No to a man in a way that will keep him coming back to become fascinated with her personality. She wants a long-term relationship, preferably a happy marriage, but she knows that if she says No to a man she'll never see him again because there are millions of other women who will say Yes. So she says Yes, and hopes he will be so charmed by what happens in the bedroom that he'll stick around and fall in love with her. Never happens, of course.
I saw this all the time among my girlfriends back when I was single. That was 25 years ago. Now I see it among some lonely single women of my acquaintance and I don't know what to tell them. The feminists have really destroyed things.
