I found a wonderful quote of what it means to be a man in Doug Phillips' book, "The Little boy Down the Road". It is found in the chapter entitled, "The Rise and Fall and Rise of Motherhood in America" on page 160.
"To be a man, you must care about women, and you must care about them in the right way. You must care about them as being worthy of protection, honor, and love. This means genuinely appreciating them for their uniqueness as women. It means recognizing the preciousness of femininity over glamour, of homemaking over careerism, and of mature motherhood over perpetual youth. But when women are reduced to soldiers, sexual objects, and social competitors, it is not merely the women who lose the identity given to them by the Creator, but the men as well. This si why the attack on motherhood has produced a nation of eunuchs---socially and spiritually impotent men who have little capacity to lead, let alone love women as God intended man to love woman--as mothers, wives, sisters, and daughters."
