Many of us don’t behave like that and wonder exactly what a man who does this values in a woman . Clearly , if he is happy to spend time sitting and choosing which women to look at based purely on the physical this is pretty high on his priorities .
See s to be a sad fact that a portion of the male population is like this i.e..looks and youth are what they value in women above all else.
The wealthy men like this swap out wives/partners as they age the non wealthy men do not have that option much if the time.
(You do get non wealthy men with a lot of Barney/game who can and do - but they're in the minority).
So the female population over 35/40, or whatever age these men seem past prime, can end up stuck with men like these who are naturally not going to say that they'd prefer a younger partner they consider hotter, but nonetheless their behaviour leaks that.
There are also men who are slightly more complicated in that it's not a straight "I'd swap her for a younger model of o had the opportunity"; they realise that socially, within their family, life stages, things in common etc. - a woman closer to their age is preferable, but sexually they'd still like to have had a young, "hot" woman and that leaks out in their behaviour.
It's an uncomfortable position to be in fir the women who are with them; you have to wonder if you're not dependant on them, don't share children with them etc.; would you be happier out of it instead of being with someone you don't respect because of their behaviour like this.
