Sexuality refers to sexual orientation, attraction, fantasies and attitudes related to sex. It includes heterosexuality, attraction to the opposite sex; homosexuality, attraction to the same sex; bisexuality, attraction to both sexes; pansexuality, attraction to all genders; asexuality, little to no sexual attraction; and queer, not conforming to traditional norms. Sexuality differs from gender, which refers to one's identity, and is distinct from biological sex. Common types of sexuality are defined and described.
