Some men simply don't "get on" with other men, so some men don't have that same network of support etc., and end up isolated with no one to talk things through with. Even those who do "go out with the lads" are highly unlikely to talk about deeper feelings etc as that's not part of their usual "banter".
My DH has, literally, no male friends. None at all. Never has had. Never gone out to the "pub with his mates" or a "footie match with the lads". He just hates the "banter", the male egos, etc.
He's always got on better with women. Always preferred to work with women, etc., and gets on better with women when he was doing voluntary work, charity work, and was a member of clubs and societies. Never broadening to any kind of "friendship" as such outside the specific environment.
It's probably why I was attracted to him in the first place as he's about the polar opposite of the "bad boy" "alpha male" "macho man" - the kind of lad/bloke that were always so popular when you're young, but who I'd never touch with a bargepole.
So yes, you really can't generalise and I believe there are lots of blokes who don't fit in the stereotype of the "typical" male. I'd also venture to say our DS is the same - he's had what I consider to be a good role model in my DH and he seems to be very popular among the females at work and in his hobby groups, not in a romantic way, but in a kind of "brother/sister/collegue" way.
I never really knew DH's father as he died within the first few months of me meeting DH, but the few times I did meet him, he seemed a very quiet and respectful kind of guy. I often think that it's good role models, DH followed his father and our DS is following my DH in respecting women for who they are rather than for anything else.
Yes, I know some posters will pile on saying all men are the same and my DH and DS are just hiding their true feelings, but I just don't believe it - the way they talk and act says otherwise.
So, yes, I do think that the "patriarchy" can be very damaging for some males who simply don't fit into the "normal" male behaviour patterns and are genuinely left out and confused.
