Klein Sexual Orientation Grid

The Klein Sexual Orientation Grid (KSOG) developed by Dr. Fritz Klein attempts to further measure sexual orientation by expanding upon the earlier Kinsey scale which categorizes sexual history from 0 (exclusively heterosexual) to 6 (exclusively homosexual). Notably, the grid cannot account for people who have had limited sexual or social opportunities or experiences.

Grid

	Past (entire life up until a year ago)	Present (last 12 months)	Ideal (what would you like?)
A). Sexual Attraction: To whom are you sexually attracted?
B). Sexual Behaviour: With whom have you actually had sex?
C). Sexual Fantasies: About whom are your sexual fantasies?
D). Emotional preference: Who do you feel more drawn to or close to emotionally?
E). Social preference: Which gender do you socialize with?
F). Lifestyle preference: In which community do you like to spend your time? In which do you feel most comfortable?
G). Self-identification: How do you label or identify yourself?

Each of the 21 boxes should contain a value from 1 to 7, categorizing the individual's answers to the questions. For variables A to E the possible answers are: 1 = Other sex only, 2 = Other sex mostly, 3 = Other sex somewhat more, 4 = Both sexes, 5 = Same sex somewhat more, 6 = Same sex mostly, and 7 = Same sex only. For variables F and G these range from 1 = Heterosexual Only to 7 = Homosexual Only.

Unlike the Kinsey Scale, the Klein grid investigates sexual orientation in three time periods and with respect to seven factors.
