Heteronormativity

Heteronormativity is the belief that people fall into distinct and complementary genders (man and woman) with natural roles in life. It assumes that heterosexuality is the only sexual orientation or only norm, and states that sexual and marital relations are most (or only) fitting between people of opposite sexes. Consequently, a "heteronormative" view is one that involves alignment of biological sex, sexuality, gender identity and gender roles. Heteronormativity is often linked to heterosexism and homophobia.
