It is easy to get distracted and misled by the fact that the sexual revolution began (mid 1960s) with an explicit assertion of the 'rights' of individuals to 'do whatever they wanted with whoever/ whatever they wanted' - the principle of open-ended and impulsive hedonism. Free love etc. - with an emphasis on extreme heterosexual promiscuity (because that is what most men 'want' at the purely-hedonic level).
The 'problem' was to persuade most women that they wanted it too. And in practice this required social indoctrination (by the fake female peer group of the mass media) and liberal usage of alcohol and drugs, and engineered pro-promiscuous social situations.
Most people fail to recognise that this ultra-libertarian and individualist 'let it all hang out', 'follow your dreams and impulses' spirit has long since been replaced by something very different in spirit: something collective, bureaucratic, totalitarian.
Perhaps the feminists began it with the slogan and idea: The personal is political.
This, unnoticed at the time, was a repudiation and reversal of carefree, individualist hedonism - and the assertion that all thought and actions (including sexual) were primarily political, hence collective, statements. At exactly this point - and, significantly, under the explicit guidance of women - began the assertion that The System had the authority, right and power to take-over sexuality.
Nowadays, the realm of sex and sexuality has been drained of hedonic significance and become a realm of earnest and hectoring political monitoring, propaganda and control - in an inverted morality by which sexual acts, including their discussion, are the primary theme used to enforce a top-down, collective ethos.
To be included in the totalitarian system, sex must be made explicit and universally discussed. But - as everyone feels and knows - the realm of sex is thereby enslaved to that system. When everything is shared socially and officially, and when that social and official realm has been absorbed into the social control system (with rewards, threats, sanctions) - we have what we recognise as modern reality of the sexual revolution.
60's sexuality was always a 'stalking horse' - a fake policy, a temporary battering ram for use against the 'repressive' Christian churches, behind which the real (global establishment) agenda was advanced.
Nowadays, the pro-impulsive sixties ethos is merely exploited as a lure (e.g. in pop videos, adverts and similar), to get people interested, to get them pro-sexual revolution with the promise of pleasure; before the transition into top-down, bureaucratic totalitarianism; where sex and sexuality becomes a controlled, symbolic demonstration of everybody's subordination to The System.
Note: For the sex n drugs n rock-and-roll generation, the sexual revolution has been a classic example of 'bait and switch'. They began as selfish, hedonic rebels; and ended as titled and awarded chairmen of bureaucracies encouraging/ celebrating/ imposing ever more laws, procedures and codes-of-practice and crushing all freedom and pleasure in the name of 'diversity' and 'inclusion'. Their always-evil-motivations are clearly revealed by the fact that so very few of them have chosen to refuse this trajectory, or even to acknowledge the U-turn in the sexual revolution. The few that have done so tend to be notorious and vilified - Camille Paglia is an example, who apparently remained an unreconstrcted 60s radical, and denied/ was refused the Establishment plaudits of her contemporaries. The System has attempted to crush her more than once, and currently.
Further Note: I refrained from the use of the (handy) Steiner nomenclature; but I am obviously describing the way that a brief Luciferic hedonic anti-System sexual revolution in the 1960s; fed-into a prolonged Ahrimanic phase (still ongoing) in which the sexual revolution is primarily a series of excuses for more bureaucracy, hence further extension and tightening of the totalitarian System. The trajectory from anti-System to Pro-System - and many individuals undergo this exact same trajectory in their own personal development - because without God The System is inevitable and supreme as the only societal source of meaning and purpose - so being anti-System is ultimately futile, and Lucifer always leads to Ahriman.
