Why is self-control so important for men?

Self-control for a man is definitely S-tier. Men are not as emotionally inclined as women, and a huge part of that is just biological. But men have enormous weaknesses when they begin to feed into their passions, especially the passion of lust. So self-control has to be S-tier. As a man you may have ups and downs in your emotions as life hits you with adversity, but even when your emotions go high, you have to remain steady and composed in your outward appearance.
