Manliness has been defined as assertion of the self. Womanliness has been defined as the nurturing of selves other than our own - even if we quite lose our own in the process. (Women are supposed to find in this loss their true fulfillment.) But every individual person is born both to assert herself or himself and to act out a sympathy for others trying to find themselves - in Christian terms, meant to love one's self as one loves others ... Jesus never taught that we should split up that commandment - assigning 'love yourself' to men, 'love others' to women. But society has tried to.
