The sexual revolution had nothing to do with feminism. It in fact is antithetical to feminism. Second-wave feminism, especially radical feminism, was born because of the lousy treatment women received by men in the antiwar and civil rights movements of the 1960s.
Kinsey, Ellis, Ginsburg, Money, Hefner, and the rest of them were to a man--and almost all of them were men--perverts and degenerates. It wasn't generally known at the time but years later what these guys were really all about. They were all about violating appropriate boundaries between the sexes and not just about overthrowing the 1950s "prudery." Queer theory/transgenderism are much more in line with the "sexual revolution" and are the end result of it than feminism ever was.
The best account of the sexual revolution of the 1960s is in Andrea Dworkin's book, Right-Wing Women, in the chapter "Abortion." She knew of what she spoke, and she was dead right.
