The American Psychological Association defines "sexual orientation" as "an enduring pattern of emotional, romantic, and/or sexual attractions to men, women, or both sexes," ranging "along a continuum, from exclusive attraction to the other sex to exclusive attraction to the same sex." Sexual orientation can also be "discussed in terms of three categories: heterosexual (having emotional, romantic, or sexual attractions to members of the other sex), gay/lesbian (having emotional, romantic, or sexual attractions to members of one's own sex), and bisexual (having emotional, romantic, or sexual attractions to both men and women)."
