During the 1940’s, Alfred Kinsey and associates shocked Americans when he first published his work on male sexuality. His controversial research challenged traditional notions of sexuality as a one-dimensional construct. Through extensive research, Kinsey et. al pioneered the first comprehensive continuum of sexuality.
5- Predominantly homosexual, only incidentally heterosexual
6- Exclusively homosexual
Building on the work Kinsey, Dr. Fritz Klein viewed sexual orientation as a "dynamic, multi-variable process.” In an attempt to measure his hypotheses, he created the Klein Sexual Orientation Grid. Klein’s work was significant because he attended to sexual and non-sexual variables, which fluctuate with time. Three factors address sexual self (attraction, fantasies, behavior), three variables focus on critical aspects of sexual orientation (emotional preference, social preference, heterosexual or homosexual lifestyle), and the final factor assesses self-identification.
