Step-by-step explanation:
Alfred Kinsey defined sexual orientation as a continuum rather than a strict dichotomy of gay or straight. He created a six-point rating scale that ranges from exclusively heterosexual to exclusively homosexual. Kinsey's scale suggests that human sexuality exists on a spectrum and is not limited to two separate categories (dichotomy).
