I've known several extremely promiscuous women from high school who got married and have stayed married. I've know some who got married and divorced and got married again. And got divorced again. Those are the ones I've seen turn into cougars.
I started noticing something different in college. I knew some promiscuous women who never got married. And some non-promiscuous ones who never got married.
What did the promiscuous ones have in common?
They were nuts. That is, narcissistic. Histrionic Personality Disorder, some sort of narcissism...things like that. I knew two whose ideas of sex lasted one minute, until they had orgasms. Then they went to sleep.
That was their problem. Self-centered, irresponsible, immature. That's why they never got married. I've know a few who were bipolar, even to the point of undergoing electroshock treatment.
What did they all have in common? "Education." You know - "female education." Worthless, make-work degrees.
For some reason "educated" women tend to have a problem with getting married. I don't know exactly why. And it doesn't happen every time. But I've seen it happen more than once - far more than once. Maybe they're more narcissistic, like the selfish, inconsiderate sluts.
