For me it's always been about women. I personally could really care less about what other men thought, I don't worry about all that alpha male peeing higher on the tree nonsense. But my experience has been that women don't want anything to do with a man that was vulnerable. What's the first thing they always say they find attractive? Confidence. Vulnerability doesn't ever even make the top 100.
So for me it's always been and will always be because of the opposite sex.
