Bi-curious is a phenomenon in which people of a heterosexual or homosexual identity who, while having some curiosity for sexual activity with a person of the sex they do not favor, distinguish themselves from the bisexual label. The term is sometimes used to describe a broad continuum of sexual orientation between heterosexuality and bisexuality. Such continuums include mostly-heterosexual or mostly-homosexual, but these can be self identified without identifying as bisexual. The terms heteroflexible and homoflexible are also applied to bi-curiosity, though some authors distinguish heteroflexibility (or homoflexibility) as lacking the "wish to experiment with ... sexuality" implied by the bi-curious label.
The term bi-curious implies that the individual has either no or limited homosexual experience in the case of heterosexual individuals, or no or limited heterosexual experience in the case of homosexual individuals, but they may continue to self-identify as bi-curious if they do not feel they have adequately explored these feelings, or if they do not wish to identify as bisexual.
