Love, for example, has been popularized to be a romantic movie-cliché where handsome guy spends his daytime on a picnic during middle of the day (middle of the week). In contract my bubble - all men I know show affection through dedication and work, which isn't perceived as very romantic.
Men are less social. There are reasons, but life right now allows us to be less social. ~50 years ago you either cooked for yourself or you went out to restaurant if you wanted to eat. Meeting people was inevitable. ~20 years ago you could call for a pizza, but that still involved human contact.
Today? I have an app for that. I also have an app for taxi, laundry, groceries, clearning etc. Remote work is getting increasingly common. I can manage my whole life not even leaving my flat without any need to talk to anyone. Some of my male colleagues actually live like that.
And social skills is not something one can get from podcast. They need to be trained and sustained, especially for those who aren't naturally talented and charismatic. And without them - good luck finding partner. There's also slippery slope involved, that some other commenters mention. It can't be I who is at fault, right? It must be THEM.
The only way out is to actually get more social, but that's something that men also don't do. There's this stigma that it must've been something wrong with man if they try to find friends.
So it's somewhat bleak future, but not grim nor unchangeable. It's just (some) men got behind and it'd be nice if there'd be help for them to catch up.
