It’s not biological. It’s social learning.
Men have just as much ability to form social bonds.

Men have the same amount of emotions. Same emotional responses.

There is a ton of research on this.

It’s our society and gender roles that keep men from having cooperative friendships.

They are told as children they have to one up each other and never cooperate. Never show sadness to other boys/men.

But they still have those feelings. And hiding them actually just creates mental health problems and behavior problems.
