The whole concept of the “Sexual Revolution” was demolished by radical feminists in the 1970s and in the later continuum works by Sheila Jeffreys.
Jeffreys has exposed the early and mid 20th century sexologists as being no more than front men for a broader and more uninhibited, male sexuality which in turn was to liberate women from both rote, limiting, disembodies sex. But, of course, even a very superficial glance into the works of any of these deSadean sexologists reveals their influential “revolution” to be a total sham.
For men it meant potential access to all women. For women it meant freedom to sleep with more men, and freedom to gratify their pleasure by learning more sexual postures, most of them debasing and pornographic. At multiple levels, it was anything but liberating, and often outright victimizing and destructive.
Heffner was just one of their wormy offspring who happened upon a little empire which he shakily offered up in tribute to his creepy sexist forefathers, never daring to cross them in any way.
