Bisexual

Bisexuality is an orientation meaning someone who is sexually or romantically attracted to people of two or more genders. These two genders are most commonly assumed to be men and women, but they do not necessarily have to be. Bisexual people do not have to attracted to both genders equally.

According to Alfred Kinsey's research in the mid-20th century, most humans are not exclusively heterosexual or homosexual. The Kinsey scale measures sexual attraction and behavior on a seven-point scale ranging from 0 ("exclusively heterosexual") to 6 ("exclusively homosexual"). It was found that most people fall somewhere in the 1-5 category.
