Kinsey scale

The Kinsey scale, introduced by Alfred Kinsey in 1948, rates sexual orientation from 0 (exclusively heterosexual) to 6 (exclusively homosexual), with X for no socio-sexual response.

A self-identification: Alfred Kinsey’s 0–6 scale (plus X) placing sexual orientation on a continuum rather than a binary. (Alfred Kinsey, 1948)
