Respect and being masculine go hand in hand.
The more a man is respected, the more he appears to others as being masculine.
Now I am not saying this is a 100% truth, but it is a working theory of mine.
You see a man who takes action and builds a business, asks for a raise, learns a new skill, or many other examples.
The thing is the man who does this creates a momentum of growing respect that others see and contribute to.
