... from Wikipedia...

Heteroflexibility is a form of a sexual orientation or situational sexual behavior characterized by limited homosexual activity despite a primarily heterosexual sexual orientation that is considered to distinguish it from bisexuality. It has been characterized as "mostly straight".^[1] Although sometimes equated with bi-curiosity to describe a broad continuum of sexual orientation between heterosexuality and bisexuality,^[2] other authors distinguish heteroflexibility as lacking the "wish to experiment with ... sexuality" implied by the bi-curious label.^[3] The corresponding situation in which homosexual activity predominates has also been described, termed homoflexibility.^[4]
