Many years ago I read an article stating that any woman dating a man should ask his friends what he's like. I thought that was good advice, because men can see through other men very rapidly. Many women, on the other hand, can't see through men at all. In my entire life I have never seen a woman ask another man what the man she is dating is reallly like.
In college I knew a guy, who was an acquaintance and not a friend, who I did not like. He never did anything to me, but I was getting red flags on him -- sort of an intuitive gut feeling.
He was a friend of a friend, though, so I got the story on him. He was the only guy I ever met who would go out of his way to manipulate and lie to women so he could have sex with them.
He'd target women who were less attractive than he was, lead to them to think he was their boyfriend, have sex with them for a few weeks, then dump them. He was the only guy in my life I've met who did this.
The women were always stunned. They had deluded themselves they were special. And I guarantee you that if my friend -- or I -- had told these women was this guy was really like, they would have never believed it. They would have thought we were trying to break them up, for whatever bizarre reason they could concoct in their fuzzy-minded heads.
Many guys, although not all, will sleep with an available attractive woman, but they won't lead her to believe he's considering her for a serious long-term relationship. This guy did, dozens of times.
I've also met female versions of this man. He, and the women, have all ended up alone, unmarried, with no children. The women have cats as surrogate children.
How did this happen?
My experience has been excessively promiscuous people are narcissistic, i.e., self-centered, exploitative, manipulative and lacking in empathy. They use people, don't know it, and in the long-run end up alone.
But why are so many people unable to see through them? In the case of women, who generally ruled by their feelings more than their reason, a manipulative, exploitative guy can connect with their feelings and thereby get them to connect with him.
Any parents with any sense, who have any understanding of their daughters, might look at them and tell them that girls tend to be more susceptible to their emotions and therefore might want to watch out for those charming, friendly, exploitative, manipulative types.
Sound sexist? Guess what? I don't care. The truth is the truth.
I remember only one girl saying anything bad about this guy. She said he had "a sneer on his face." And he did. That sneer was because, ultimately, I don't think he liked women. And the promiscuous women I knew, I think that they really didn't like men.
Women's blind spot is they are are ruled by their feelings, are not rational, and fall for a guy who can connect with their feelings, even if he is a lowlife.
Forewarned, as always, is forearmed.
