Gender systems are the social structures that establish the number of genders and their associated gender roles in every society. A 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, female, or androgynous. This includes but is not limited to sexual and erotic arousal and response."^[1]: 114 Gender identity is one's own personal experience with gender role and the persistence of one's individuality as male, female, or androgynous, especially in self-awareness and behavior. A gender binary is one example of a gender system.
