Men do not have a feminine side.
Creativity, nurturing, are not feminine qualities. They are human qualities. And men express them in a masculine way, as women express them in a feminine way.
Culture tries to view gender as fluid. But it is not.
Men are men. Women are women.
Understanding that it’s not wrong for a man to be more sensitive and gentle, or for a man to be more tough or aggressive is important.
Sensitivity and gentleness can be very masculine, and can be expressed by a man in a masculine way. We do not need to ascribe these kinds of qualities only to femininity.
