Pansexuality or anthrosexuality (anthro- literally meaning human, human sexual) (sometimes referred to as omnisexuality is a sexual orientation characterized by the potential for aesthetic attraction, romantic love, and/or sexual desire for people, regardless of their gender identity or biological sex. Thus, pansexuality includes potential attraction to people (such as transgender individuals) who do not fit into the gender binary of male/female. Some pansexuals suggest that they are gender-blind; that gender and sex are insignificant or irrelevant in determining whether they will be sexually attracted to others.
The word pansexual is derived from the Greek prefix pan-, meaning "all". "All" is specifically in reference to human genders. In its simplest form, pansexuality denotes the potential of sexual attraction to all genders. It is intended to negate the idea of two genders (as expressed by bi-).
The adjective pansexual may also be applied to organizations or events. In this context, the term usually indicates an openness to the involvement of people of all genders and sexual orientations in said organization/event, and to the pansexual sexual identity.
Pansexuality versus bisexuality
The terms "pansexual" and "bisexual" are not mutually exclusive. Pansexuality is inclusive of bisexuality (attraction to both males and females) but additionally includes attraction to other genders and sexes such as those identifying as transgender, genderqueer, bigender, intersex, or genderfuck. In this sense, it necessarily rejects the concept of a gender binary, which some bisexuals may not reject. To this end, pansexuality as a concept has been criticized as a "means to skip the binaries and essentialism of 'bi'."
