# Outline of human sexuality

The following outline is provided as an overview of and topical guide to human sexuality:
Human sexuality is the capacity to have erotic experiences and responses. Human sexuality can also refer to the way one person is sexually attracted to another person of the opposite sex (heterosexuality), the same sex (homosexuality), or having both tendencies (bisexuality). The lack of sexual attraction is referred to as asexuality. Human sexuality impacts cultural, political, legal and philosophical aspects of life, as well as being widely connected to issues of morality, ethics, theology, spirituality, or religion. It is not, however, directly tied to gender.
