Bisexuality is a sexual orientation which refers to the aesthetic, romantic, or sexual attraction of individuals to other individuals of either gender or sex. Most bisexuals are not equally attracted to men and women.In the mid-1950s, Alfred Kinsey devised the Kinsey scale in an attempt to measure sexual orientation. The 7 point scale has a rating of 0 ( exclusively heterosexual ) to 6 ( exclusively homosexual ). Bisexuals cover most of the scales values (1-5) which ranges between predominantly heterosexual, only incidentally homosexual (1) to predominantly homosexual, only incidentally heterosexual (5). In the middle of the scale (3) is equally heterosexual and homosexual .Although observed in a variety of forms in human societies and in the animal kingdom throughout recorded history, the term bisexuality (like the terms hetero- and homosexuality ) was only coined in the 19th century.
