Pansexuality encompasses all kinds of sexuality. It differs, however, from pansexualism, a perspective that declares “all desire and interest are derived from the sex instinct.” Pansexuality includes heterosexuality, homosexuality, bisexuality, and sexual behavior that does not necessarily involve a coupling. It includes, for example, masturbation, celibacy, fetishism, and fantasy. Moreover, pansexuality includes heteroerotic and homoerotic play and sexual aggression, sometimes mislabeled as “horseplay.”
