The sexual revolution of the 1950s and 1960s was based on the ideas of three atheist men: Sigmund Freud, Alfred Kinsey, and Hugh Hefner, although the doctrines of the sexual revolution ... had their roots in the "free love" movement of Marxism in the 1840s and in Margaret Sanger's writings in the early 20th century. 
Freud claimed that sexual desire could not be controlled or channeled without causing harm to one's psyche. In his model of mental illness, repression would lead to neurosis, because of the dictates of the unconscious mind.
Kinsey applied the techniques of scientific and statistical investigation to human sexuality, ignoring the taboos that previously prevented research in the field. Anonymous surveys showed that what most people considered socially unacceptable sexual practices, including homosexuality and frequent masturbation, were far more common than had been widely believed.
Hefner's "playboy philosophy" was merely a retread of Hedonism, an entirely self-centered pleasure-based life (see also Utilitarianism). What Kinsey did for the science of sex, Hefner did for its popular image - weakening taboos and allowing open discussion.
The sexual revolution gained great traction in the 1960's with the invention of the birth control pill, and in the 1970's with the legalization of abortion, as these helped separate sexual activity from the consequence of pregnancy. With sex now reduced to a low-risk activity, the deterrent against premarital or casual sex and promiscuity was greatly reduced. Sex purely for recreation became possible, without the need for a married family to raise any children produced. This began weakening the social significance of marriage - long-term sexual relationships without the need for marriage became increasingly common.
In response to the sexual revolution, American conservative groups laid policies to restore the lost connection between sex, reproduction and marriage and to set up education programs to reinforce the importance of confining sex to married relationships only. This approach eventually formed what would become abstinence only education.
|Gilbert Keith Chesterton, essay “The Next Heresy”, 1926:|
|“For the next great heresy is going to be simply an attack on morality; and especially on sexual morality. And it is coming, not from a few Socialists surviving from the Fabian Society, but from the living exultant energy of the rich resolved to enjoy themselves at last, with neither Popery nor Puritanism nor Socialism to hold them back … The madness of tomorrow is not in Moscow, but much more in Manhattan.”|
Early historical roots and parallels
In the 2nd century AD, one of the heretical sects established by Marcion embraced the basic Gnostic convictions that The God of the Old Testament is not Father of Jesus Christ, but an inferior deity who was ignorant and vengeful, foreign to the principle of "unlimited love" taught by their version of Jesus. They regarded the created world we live in as a miserable product of this inferior deity who also devised the degrading method of sexual reproduction. Thus, Marcion rejected marriage and required that his followers should not help this "malevolent" creator to keep the miserable show going on. Some Gnostics turned the argument the other way and maintained that since this mortal body will perish in any case, it does not hurt the divine spark within you if you let the body to have the sensual, mostly sexual, pleasures it longs for. These heretical views represented so serious challenge to the early church that the church father Tertullian devoted several years to writing five monumental books refuting Marcion.
Influence of Cultural Marxism
cultural marxists including György Lukác, representant of the Frankfurt School, promoted to America what later became known as cultural terrorism: radical sex education in public schools, covering such subjects as free love, outdatedness of monogamy, irrelevance of religion and the archaic nature of middle class family. Women were called upon to rebel against sexual mores of the day, such being the core values to Christianity and Western culture. His ideas later became the basis for the sexual revolution embraced by a generation of drug-challenged baby-boomers.
