In the area I grew up in I knew girls who were having sex at 13, 14, 15. All of them were promiscuous and as far as I could tell, had not-so-good relationships with their fathers. I do remember the 14-year-old ended up in some sort of home for wayward girls.
My gut, even then, told me it had something to do with the parents. Studies have confirmed my intuition: one at Texas Christian University "found [girls]...who had unstable or non-existent paternal relationships were more likely to lose their virginity at an earlier age and display risky sexual behaviors."
In college, long before any studies, I noticed the same thing. All of them didn't have the best relationships with their fathers. One told me her father repeatedly molested her. She said he took her for trips to the local lakes, and she said it so casually I was almost speechless. (Did the mother know about it and ignore it? That happens a lot.) I have no idea what happened to her, but I clearly remember she made a pass at me while the guy she came over with was asleep on the couch. I declined, since the guy was my best friend.
One woman, years later, parroted that trendy psychobabble nonsense about how she now "loved myself" after seeing a therapist for years. Yet there was still something to what she said. She also told me some of the guys she never even kissed, which I have noticed about these women myself. It's as if they don't even like the guys. (This one asked me "Did we sleep together?" because she did not remember.)
Many of these woman didn't get married, or if they did, got divorced. Some, fortunately, have had children and remained married. And most of them who did not get married were stuffed to the gills on psychiatric "medication" - which about 25% of woman are.
So, I came to the conclusion many years ago that female promiscuity had something to do with poor "self-esteem," which came from having poor relationships with their fathers. And mothers.
I've even heard it called a form of "self-mutilation." Whatever it is called, I think it is, ultimately, a search for love.
If excessive promiscuity is usually due to a poor relationship with a father, and is a search for love, then the break-up of marriages (or their failure to form) is going to lead to promiscuous girls who are unable to sustain a successful relationship with a man. This is the main reason I refer to women who purposely have have children without being married as "monsters."
And what is the divorce rate these days? At least 50%? If most of the children are given to the mother, that means...no father. It's certainly the height of female rationalization and self-delusion to think they can raise children by themselves and think they'll turn out just fine.
And the word "monster," as I have noted before, means "warning," and "demonstration." Robbins noted the same thing in his quote above: you can be a warning, or you can be an example.
I am as opposed to leftism and feminism (which is leftist) as can possibly be. Leftists want to destroy society because they want to remake it. It never works as it's supposed to, though. And they don't care who gets hurt as long as they feel all warm and fuzzy inside.
Actually, I am reminded of that saying from the Bible about how the iniquity of the fathers - and mothers, too - are visited on the children, unto the third and the fourth generations.
It's up to men to fix this problem. Women sure as hell can't. Many of them can't even see the problem.
By the way, every promiscuous guy I've known has mutilated himself, too.
