Men of course socialize in many activities but if they are shy it’s difficult the break into any clique unless you excell at something. It’s easy if you’re a great footballer or a rugby player. The same with dating it’s easy if you’re confident, men dont even have to be good looking to get attention, but being shy and awkward gets you dismissed as creepy or a geek.
Men dont talk about their problems, it’s not manly, not macho, they retreat into solitary activities, video games is a good example, I know a couple who are computer experts who spend their whole waking hours designing software and computers.
Men’s sheds are older men usually retired and would not appeal to the younger set who if they are unemployed get directed to voluntary work.
To be honest my sympathies go to young women who cannot find a partner to settle down with, if they have children it’s even more difficult
