It’s a presence of mind within the males make up, pertaining to how they take care, (support, nurture, love, discipline) those that are more vulnerable than themselves. Most ppl describe it in a physical sense, but once you feel and see it in a human, especially a man, (father, husband, boyfriend, son, nephew) in a spiritual or personality trait) it becomes increasingly obvious if a man inhabits his masculinity. We have not evolved too differently over 100,000 years. A good man who inhabits his masculinity, still ultimately wants to provide for his family. If they get it right, it’s a powerful life force.
