The term "Sexual Revolution" has been used at least since the late 1910s Some early commentators believed the sexual revolution of 1960–1980 was in fact the second revolution in America, they believe that the first revolution was during the Roaring Twenties after World War I and it included writers such as F. Scott Fitzgerald, Edna Saint Vincent Millay, and Ernest Hemingway. However the sexual revolution that began in the late sixties among college-age hippies was reaching mainstream, middle class, even middle aged America. The revolution was recognized by profound shifts in the attitudes on women’s sexuality and homosexuality, and the freedom of sexual expression. Writers of Freudian theories such as William Reich and Alfred Kinsey sparked the revolution along with the battle of pornography and the right to free sexual speech; and the social movements of the time period contributed to the revolution including the counterculture movement, women’s movement, and the gay rights movement.The Counterculture contributed to the awareness of radical cultural change that was the social matrix of the sexual revolution.The sexual revolution had shifted how we think about sexuality in two different ways. One way was the development of ideas proceeded from tremendous strides in sex research, and technological advances in birth control; but on another level the ideas of the revolution grew out of everyday lives of the men and women who refused to obey the codes of behavior from their parents, resisted the etiquette of polite language, expressed sexual fantasies in media and exploited sexual imagery to sell commodities.Nisker cites the San Francisco Oracle, which described the 1967 Human Be-In as a "spiritual revolution". In the late 1970s and 1980s, newly won sexual freedoms were exploited by big businesses looking to capitalize on a more open society, with the advent of public and hardcore pornography.Historian David Allyn argues that the sexual revolution was a time of "coming-out": about premarital sex, masturbation, erotic fantasies, pornography use, and sexuality
