The Klein Sexual Orientation Grid attempts to further measure sexual orientation by expanding upon the earlier Kinsey scale which only considers from 0 (exclusively heterosexual) to 6 (exclusively homosexual). Sexual orientation describes the direction of an individuals sexuality, often in relation to their own sex or gender. ... The Kinsey scale attempts to measure an individuals sexual orientation, from 0 (exclusively heterosexual) to 6 (exclusively homosexual), in terms of the biological sex of their former sexual partners. ... Heterosexuality is a sexual orientation characterized by esthetic attraction, romantic love or sexual desire exclusively for members of the opposite sex or gender, contrasted with homosexuality and distinguished from bisexuality and asexuality. ... Since its coinage, the word homosexuality has acquired multiple meanings. ...

Because most people had been (and arguably still are) first exposed to sexuality with the binary of heterosexual or homosexual, Alfred Kinsey set his scale of sexual orientation with seven intervals, beginning at 0 with ‘Exclusively Heterosexual’ and concluding at 6 with ‘Exclusively Homosexual’. As you travel the scale, you could be determined to be ‘Predominantly heterosexual, more than incidentally homosexual’ at interval 2, ‘Predominantly homosexual, only incidentally heterosexual’ at interval 5 and anywhere in between. At the centre, Interval 3 is `Equally Heterosexual and Homosexual'. Dr. Alfred Charles Kinsey (June 23, 1894 – August 25, 1956), was an American biologist and professor of entomology and zoology who in 1947 founded the Institute for Research in Sex, Gender and Reproduction at Indiana University Bloomington, now called the Kinsey Institute for Research in Sex, Gender and Reproduction. ... The Kinsey scale attempts to measure an individuals sexual orientation, from 0 (exclusively heterosexual) to 6 (exclusively homosexual), in terms of the biological sex of their former sexual partners. ...

Fritz Klein refined the scale and somewhat simplified it. It remains with 7 intervals, but instead they are: This article is about the sex researcher; for other people named Fritz Klein, see Fritz Klein (disambiguation). ...

What limits the Kinsey scale is that it focuses on the person’s sexual experiences and fantasies up to that time. So to develop and hope for a better understanding of an individual’s sexuality throughout their lives, the Klein scale investigates sexual experience and fantasies in three times: the present (the most recent 12 months), the past (up to 12 months ago) and the ideal (which is as close as one can get to intention and prediction of future behaviour). The Kinsey scale attempts to measure an individuals sexual orientation, from 0 (exclusively heterosexual) to 6 (exclusively homosexual), in terms of the biological sex of their former sexual partners. ...

Basically, Klein allowed the concept that people’s sexuality can change through their lives.

But these aren’t the only innovations Klein made. Even more important than considering that sexuality is fluid was Klein's introduction of many different factors that can influence identity. These are: Fluid Sexuality is when a persons sexuality changes over a long period of time. ...

• Sexual Attraction: To whom are you sexually attracted?
• Sexual Behaviour: With whom have you actually had sex?
• Sexual Fantasies: About whom are your sexual fantasies? (They may occur during masturbation, daydreaming, as part of real life, or purely in your imagination.)
• Emotional Preference: Emotions influence, if not define, the actual physical act of love. Do you love and like only members of the same sex, only members of the other sex, or members of both sexes?
• Social Preference: Social Preference is closely allied with, but often different from emotional preference. With members of which sex do you socialize?

By considering all of these other life factors, Klein's categorical scale offers much more in terms of understanding that sexual activities do not necessarily denote sexual orientation, and just because two people have the same sexual identity does not mean that they have the same sexual practices. Sexual orientation describes the direction of an individuals sexuality, often in relation to their own sex or gender. ... Sexual identity is the sex with which a person identifies, or is identified. ...
