Yes, that’s part of the societal expectations and conditioning that I’m talking about. Men are told to keep their emotions completely hidden by most people around them.

the last thing they want is a man that can’t handle his own problems.

It even sounds like you’re describing one of the things I was alluding to in my comment, that it’s stifling for heterosexual relationships when the man can only unload emotional burdens on their partner and nobody else. It’s a burden on both sides when that happens, and men need emotional outlets through diverse relationships in their lives with friends, family members, and their significant other.
