I’ve seen it repeated on here multiple times and as someone who has actually studied the issue it’s a widely ahistorical take. The sexual revolution was not primarily started by women or feminist, there were multiple movements whose goal was breaking out of the traditional sexual framework in Western society at that moment and towards a more sexually liberating one.

First there was Alfred Kinsey and his studies which raised public consciousness on sexuality.

In the late 1940s and early 1950s, Alfred C. Kinsey published two surveys of modern sexual behavior. In 1948 Alfred C. Kinsey and his co-workers, responding to a request by female students at Indiana University for more information on human sexual behavior, published the book Sexual behavior in the Human Male. They followed this five years later with Sexual behavior in the Human Female. These books began a revolution in social awareness of, and public attention given to, human sexuality.

Then there was the creation of playboy culture, which as early as the 1950s was advocating for the bachelor lifestyle, fighting obscenity laws to normalize pornography/nudity, promoting premarital sex etc.

In 1953, Chicago resident Hugh Hefner founded Playboy, a magazine which aimed to target males between the ages of 21 and 45.[27] The coverpage and nude centerfold in the first edition featured Marilyn Monroe, then a rising sex symbol.[28][29] Featuring cartoons, interviews, short fiction, Hefner's "Playboy Philosophy" and unclothed female "Playmates" posing provocatively, the magazine became immensely successful.[27]

In 1960, Hefner expanded Playboy Enterprises, opening the first Playboy Club in Chicago,[27] which grew to a chain of nightclubs and resorts. The private clubs offered relaxation for members, who were waited on by Playboy Bunnies.[27]

While Hefner claimed his company contributed to America's more liberal attitude towards sex,[27] others believe he simply exploited it.

This would later lead to the explosion of the pornography industry and nudie magazines.

In 1971 Playboy stopped airbrushing pubic hair out of its centerfold picture spreads; this new addition caused the magazine to hit its all-time peak circulation of more than seven million copies in 1972 and men started having more choices when it came to magazines.[22]

In 1972 Deep Throat became a popular movie for heterosexual couples. The movie played all over America and was the first porn movie to earn a gross of a million dollars.[22]

Pornography was less stigmatized by the end of the 1980s, and more mainstream movies depicted sexual intercourse as entertainment. Magazines depicting nudity, such as the popular Playboy and Penthouse magazines, won some acceptance as mainstream journals, in which public figures felt safe expressing their fantasies.

And finally there was the hippy movement of free love which sought to rebel against 1950s sexual mores.

Free love is a social movement that accepts all forms of love. The movement's initial goal was to separate the state from sexual matters such as marriage, birth control, and adultery. It stated that such issues were the concern of the people involved, and no one else.[54]

There was a feminist section of the sexual revolution that sought to sexual liberation and fulfillment for women especially queer women.

Coinciding with second-wave feminism and the women's liberation movement initiated in the early 1960s, the sexual liberation movement was aided by feminist ideologues in their mutual struggle to challenge traditional ideas regarding female sexuality and queer sexuality. Elimination of undue favorable bias towards men and objectification of women as well as support for women's right to choose her sexual partners free of outside interference or judgment were three of the main goals associated with sexual liberation from the feminist perspective.

However, to say that feminists were the driving force behind the sexual revolution is simply false especially considering a lot early feminist were quite critical of some aspects of the sexual revolution especially playboy culture and the hippie movement. Mass media and the hippie movement played a larger role imo.
