As a trans women, I have a unique perspective on how gender impacts social relations having lived life in each of the two worlds.
Like commenters above mention, emotional support is table stakes in friendship among women. It is a kinder, gentler world - the kind of world you perhaps remember growing up in. That world still exists, but it's typically not accessible to men once they reach adulthood.
How could men access the world of emotional support? By disassociating the idea of gender and emotional support. Growing up in the 90s and 2000s, I remember emotional vulnerability being associated with homosexuality - it was "gay" for men to be emotionally vulnerable with eachother, typically leaving men with women[spouses] or family members as their only source of emotional support. The way out is decouple these two things, to un-"gay" emotional vulnerability between men.
What does it look like? Checking in on friends, learning to open up yourself, increasing emotional intelligence, learning how to hold space and reflectively listen. Not trying to solve people's problems when what they want is to be heard. All of these skills and norms exist within feminine spaces as a matter of course and when folks say "putting in the work" it means learning to employ these things.
It means that being emotionally vulnerable doesn't imply a sexual advancement. It means enforcing that as a reality.
