After years of research, depth psychologists and others argue that each sex carries both the psychological and physical traits of the other. No man is purely masculine, just as there is no purely feminine woman. Jungian psychologists call the feminine characteristics of the male psyche the Anima; the female psyche's masculine characteristics they the Animus.  Both the Animus and Anima develop in complex fashion as the personality grows to maturity. Neither men nor women can reach psychological maturity without integrating their respective contrasexual other. A man's female elements enhance his manhood, just as a woman's male aspects enhance her womanhood.
