Wow very interesting read, I guess after reading this I grew up pretty lucky having a good group of guy friends who didn't care I was gay and living in a place where "toxic masculinity" was to that extent.
I do think though guys at least where I'm from are getting better about opening up about feelings I know plenty of guys who openly talk about going to therapy, dealing with depression, etc. Hopefully one day everyone can just be themselves without caring about what others think, I believe thats what it all boils down to.
