What is Scales of sexual orientation?

Scales of sexual orientation are classification schemes of different sexual orientations. Definitions of the term sexual orientation normally include two components: the "psychological" and the "behavioral" component, but definitions of the two components vary between researchers and across time. Those difficulties motivate researchers to define scales to measure and describe sexual orientation. Most sexual behavior and sexual orientation scales are motivated by the view that sexual orientation is a continuum. The Kinsey scale works from a continuum viewpoint and is the most prevalent sexual orientation scale.
