The institute believes that the notion that if a person identifies as bisexual, then it is a reinforcement of a false gender binary is a notion that "has its roots in the anti-science, anti-Enlightenment philosophy that has ironically found a home within many Queer Studies departments at universities across the Anglophone world" and that "while it is true that our society's language and terminology do not necessarily reflect the full spectrum of human gender diversity, that is hardly the fault of people who choose to identify as bi. [...] The Latin prefix bi- does indeed indicate two or both, however the 'both' indicated in the word bisexual are merely homosexual
(lit. same sex) and heterosexual
(lit. different sex)." The institute argues that heterosexuality and homosexuality, by contrast," are defined by the boundary of two sexes/genders. Given those fundamental facts, any criticism of bisexuality as reinforcing a gender binary is misplaced. Over time, our society's concept of human sex and gender may well change."
The term pansexuality
is sometimes used interchangeably with bisexuality
, and, similarly, people who identify as bisexual may "feel that gender, biological sex, and sexual orientation should not be a focal point in potential [romantic/sexual] relationships."
In one study analyzing sexual identities described as alternative terms for bisexual or bi-self labels, "half of all bisexual and bisexual-identified respondents also chose alternative self-labels such as queer
, pansensual, polyfidelitous, ambisexual, polysexual,
or personalized identities such as 'byke' or 'biphilic'".
Polysexuality is similar to pansexuality in definition, meaning "encompassing more than one sexuality," but not necessarily encompassing all sexualities. This is distinct from polyamory
, which means more than one intimate relationship at the same time with the knowledge and consent of everyone involved. American Institute of Bisexuality stated, "The term fluid
expresses the fact that the balance of a person's homosexual and heterosexual attractions exists in a state of flux and changes over time."
