gender-identity/role (G-I/R): gender identity is the private experience of gender role, and gender role is public manifestation of gender identity. [Both are like two sides of the same coin, and constitute the unity of G-I/R.] Gender identity is the sameness, unity, and persistence of one's individuality as male, female, or [androgynous]{ambivalent}, in greater or lesser degree, especially as it is experienced in self-awareness and behavior. Gender role is everything that a person says and does to indicate to others or to the self the degree that one is either male or female or [androgynous]{ambivalent}; it includes but is not restricted to sexual and erotic arousal and response (which should never be excluded from the definition).
