Heteroflexibility is a form of a sexual orientation or situational sexual behavior characterized by minimal homosexual activity in an otherwise primarily heterosexual orientation that is considered to distinguish it from bisexuality. It has been characterized as "mostly straight".
Bisexuality is romantic attraction, sexual attraction, or sexual behavior toward both males and females, or romantic or sexual attraction to people of any sex or gender identity; this latter aspect is sometimes alternatively termed
pansexuality.
