2. Kinsey Scale
The Heterosexual-Homosexual Rating Scale, sometimes referred to as
the “Kinsey Scale,” was developed by Alfred Kinsey and his colleagues
Wardell Pomeroy and Clyde Martin in 1948, in order to account for
research findings that showed people did not fit into neat and
exclusive heterosexual or homosexual categories.
Interviewing people about their sexual histories, the Kinsey team
found that, for many people, sexual behavior, thoughts and feelings
towards the same or opposite sex was not always consistent across
time. Though the majority of men and women reported being
exclusively heterosexual, and a percentage reported exclusively
homosexual behavior and attractions, many individuals disclosed
behaviors or thoughts somewhere in between.

Sexuality Rating Scale
• 0- Exclusively heterosexual with
no homosexual
• 1- Predominantly heterosexual,
only incidentally homosexual
• 2- Predominantly heterosexual,
but more than incidentally
homosexual
• 3- Equally heterosexual and
homosexual
• 4- Predominantly homosexual,
but more than incidentally
heterosexual
• 5- Predominantly homosexual,
only incidentally heterosexual
• 6- Exclusively homosexual

5. Klein Sexual Orientation Scale
The Klein Sexual Orientation Grid (or KSOG) is a system for
describing a person's sexual proclivities in a way more detailed
and informative than previous methods. It was introduced by Dr.
Fritz Klein (1932-2006) in his book The Bisexual Option.
6. Dr. Fritz Klein
Sexual Orientation Grid - (Bisexuality)
• For variables A to E:
• 1 = Other sex only
Variable Past Present Ideal
2 = Other sex mostly
3 = Other sex somewhat more
Sexual Attraction
4 = Both sexes
A 5 = Same sex somewhat more
Sexual Behavior 6 = Same sex mostly
B
7 = Same sex only
C
Sexual Fantasies
• For variables F and G:
D
Emotional Preference • 1 = Heterosexual only
2 = Heterosexual mostly
E
Social Preference
3 = Heterosexual somewhat more
Heterosexual/Homosexual Lifestyle
4 = Hetero/Gay-Lesbian equally
F 5 = Gay/Lesbian somewhat more
Self Identification
6 = Gay/Lesbian mostly
G
7 = Gay/Lesbian only
• Definitions helpful in using the Klein scale*:
• Past: Your life up to 12 months ago.
Present: The most recent 12 months
Ideal: What do you think you would
eventually like?
7. Klein Sexual Orientation Scale
The Variables:
• Sexual Attraction: To whom are you sexually attracted?
• Sexual Behavior: With whom have you actually had sex?
• Sexual Fantasies: Whom are your sexual fantasies about? (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?
• Lifestyle Preference: What is the sexual identity of the people with whom you
socialize?
• Sexual Identity: How do you think of yourself?
• Political Identity: Some people describe their relationship to the rest of society
differently than their personal sexual identity. For instance, a woman may have a
heterosexual sexual identity, but a lesbian political identity. How do you think of
yourself politically?
8. Storms Scale
Storms’ model is a two-dimensional map of erotic orientation showing
four sexual orientation categories: homosexual, bisexual, asexual, and
heterosexual. This model was proposed in 1979 by Michael Storms to
address several inadequacies with the one-dimensional Kinsey scale.
First, the Kinsey scale had no way to distinguish between strong
attraction to males and females and little to no attraction to either.
Associated with this, Kinsey had no way of dealing with asexuals and
simply labeled them X, a point completely off of the scale. By placing
hetero- and homo-eroticism on two perpendicular axes, Storms' model
can both account for asexuality, which fits poorly into the bipolar
Kinsey scale, and more accurately describe bisexuality.
In addition to this, the Storms model makes an interesting prediction
regarding asexuals (that Storms did not mention): Asexuals should
exist along a continuum with non-asexuals rather than being an
inexplicable anomaly that must be placed off the scale.
9. Michael D. Storms
Storms Model – (Asexuality vs. Demi-Sexuality)
Michael Storms proposed this new scale using an
X and Y axis in 1980.
Contributions:
• Includes an Asexual Identity
• Simultaneously expresses Homo- and
Heteroeroticsm
• Portrays sexuality as less linear
• Not just variation on the hetero homo
dichotomy.
Limitations:
• Attempts to make boundaries to the
Identities
• Forces an Identity based on eroticism (does
not allow
• for self identification)
• Depicts Asexuality as a ‘negative’
identity/eroticism
