Gender systems can affect what personal experience of one's own gender and how they fit in society?
Gender systems Gender systems are systems of gender roles in societies. 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." 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.
Womb and vagina envy In feminist psychology, the terms womb envy and vagina envy denote the anxiety that many men may feel caused by envy of the biological functions of the female sex (pregnancy, parturition, breast feeding). These emotions could fuel the social subordination of women, and drive men to succeed in other areas of life, such as business, law, and politics. Each term is analogous to the concept of female penis envy, derived from the theory of psychosexual development, presented in Freudian psychology; they address the gender role social dynamics underlying the "envy and fascination with the female breasts and lactation, with pregnancy and childbearing, and vagina envy [that] are clues and signs of transsexualism and to a femininity complex of men, which is defended against by psychological and sociocultural means".
