Bi-curious is a phenomenon in which people of a
heterosexual or
homosexual identity who, while showing some curiosity for a relationship or 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. The terms
heteroflexible and
homoflexible are also applied to bi-curiosity, though some authors distinguish heteroflexibility as lacking the "wish to experiment with ... sexuality" implied by the bi-curious label.
