That's because they have fewer options and need a life raft.
No doubt, plenty of woman get insecure as they age.
Many want a man to take care of them . Single moms want help raising their kids
My personal experience is VERY different.
Successful women don't want a wimpy guy who's afraid to speak up .
BUT,they won't put up with some loud mouth , drunken wife beater or overly controlling man.
In my marriage, when I disagree with my wife, I do so in a firm but polite and calm manner.
Since she loves and respects me , that tends to work well.
