Bi-curious (sometimes bicurious) is a term for a person, usually someone who is a self-identified heterosexual, who is curious or open about engaging in sexual activity with a person whose sex differs from that of their usual sexual partners.[1][2][3] The term is sometimes used to describe a broad continuum of sexual orientation between heterosexuality and bisexuality.[4] Such continuums include mostly heterosexual or mostly homosexual, but these can be self-identified without identifying as bisexual.[5][6] The terms heteroflexible and homoflexible are mainly applied to bi-curious people, though some authors distinguish heteroflexibility and homoflexibility as lacking the "wish to experiment with sexuality" implied by the bi-curious label. It is important when discussing this continuum to conclude that bisexuality is distinct from heterosexuality and homosexuality rather than simply an extension of said sexualities like the labels heteroflexibility and homoflexibility would imply, due to the prominent erasure and assimilation of bisexuality into other identity groups.[5] To sum it up, the difference between bisexual and bicurious is that bisexual people know that they are sexually attracted to both genders based on personal experience. Bicurious people are still maneuvering their way through their sexuality.[7][8]
Bi-curious is not to be confused with forms of sexual fluidity, defined as a "capacity for situation-dependent flexibility in sexual responsiveness,"[9] as bi-curious implies the existence of one set sexuality for the individual who carries the label, even if it is currently unknown, rather than an acknowledgment that the individual's sexual preference has changed and will continue to change that comes with sexual fluidity.
