Heteroflexible is Defined as a sexual orientation characterized by situational sexual behavior in which a person will be primarily heterosexual but, in certain situations, will find members of the same sex attractive and might even engage in homosexual behavior.
Someone who is heteroflexible is different from someone who is bisexual in the sense that he/she is mainly heterosexual. The term is colloquially known as ‘mostly straight’ or ‘bent.'
Heteroflexibility is common during the stage in a person’s life when he/she is experimenting with sexuality.
