The Table of Diversity Element, Bisexual (), is in the third column, Sexual Orientation, on the Table of Diversity.

"Bisexuality is a sexual orientation, and bisexual (commonly abbreviated to 'bi') people are those who have the capacity to form attraction and/or relationships to more than one gender. Bisexual advocate Robyn Ochs' popular definition of bisexuality is, 'The potential to be attracted- romantically and/or sexually- to people of more than one sex and/or gender, not necessarily at the same time, not necessarily in the same way, and not necessarily to the same degree."
