Answer:
Alfred Kinsey
Step-by-step explanation:
Alfred Kinsey is known to be the father of sexual revolution. He proposed that one's sexual orientation is not just limited to two categories: homosexual and heterosexual. In a bid to explain the levels of sexual orientation, he created a scale, called the Kinsey scale. This Kinsey scale ranges form 0, denoting exclusively heterosexual and 6, denoting exclusively homosexual, he concluded that the seven categories from 0 to 6 doesn't fully capture one's sexual orientation, but on a continuum between exclusively homosexual and exclusively heterosexual.
