Ask Dr. Cullins: LGBTQ



Q:  In a conversation about sex, a friend made a reference to something called the "Kinsey scale." What is that?

A:  The Kinsey scale is a way to rate a person's sexual orientation. It was developed by biologist Dr. Alfred Kinsey and his associates in the late 1940s and early 1950s. The seven points on the scale show the range of sexual orientation in humans that was reported in Dr. Kinsey's surveys. Kinsey used the word heterosexual to describe people who desire sex with people of the other gender. He used homosexual to describe people who desire sex with people of the same gender. The Kinsey scale categories are
0 — exclusively heterosexual
1 — predominantly heterosexual, infrequently homosexual
2 — predominantly heterosexual, but more than infrequently homosexual
3 — equally heterosexual and homosexual (bisexual)
4 — predominantly homosexual, but more than infrequently heterosexual
5 — predominantly homosexual, infrequently heterosexual
6 — exclusively homosexual

Today, many sexologists see the Kinsey scale as a little simplistic. They suggest that sexual orientation is more complex. But the Kinsey scale is still often used.
