thumb|Bi-curious flag Bi-curious (also bicurious) describes 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. 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.

Heteroflexibility is a form of a sexual orientation or situational sexual behavior characterized by minimal homosexual activity in an otherwise primarily heterosexual orientation, which may or may not distinguish it from bisexuality. It has been characterized as "mostly straight". Although sometimes equated with bi-curiosity to describe a broad continuum of sexual orientation between heterosexuality and bisexuality, other authors distinguish heteroflexibility as lacking the "wish to experiment with ... sexuality" implied by the bi-curious label.

Sapphism is an umbrella term for women loving women (WLW); any woman attracted to women or in a relationship with another woman, regardless of their sexual orientations, and encompassing the romantic love between women. It is the female equivalent of Uranian and Achillean.
