men who only want women for sex

No, it think they would be classified as normal. Not that their aren't a lot of men willing to delve into other aspects of a relationship to achieve that end though.

if they do dangerous or illegal things to get as many women as they can possibly have, then i would say probably.
if they just devote a lot of time & effort to getting as many women as possible, then i'd say that's pretty much along a normal spectrum of male behavior.

statements like the one i'm about to make often get dismissed as crude reductionist thinking, but the ways males & females of all species behave makes a lot of sense if you simply remember:
males have an effectively limitless supply of sperm.
females have a limited amount of eggs.

Biology is one thing but it's a bit Cro-Magnon to put all your eggs in one basket for something that has such such a brief payoff. As someone that once had a sex addiction I do think focusing on one aspect of relating to another human being can be like a drug and is an escape from dealing with real life.

normal

I would assume they think that’s the only value a woman has. A man like this is ignorant and wouldn’t be able to hold his own in a conversation with a real woman.

there are women who only want men for sex. As long as everyone is on the same page and all is consensual, there is nothing psycho about it. Isn’t that the whole basis for “friends with benefits” and “booty calls”?

maybe dad is lonely.

Think about it this way, those men tend to get eaten alive by women who only want men for their resources.
