It is said that at the time, public morality severely restricted open discussion of sexuality as a human characteristic, and specific sexual practices, especially sexual behaviours that did not lead to procreation. Kinsey's books contained studies about controversial topics such as the frequency of homosexuality, and the sexuality of minors aged two weeks to fourteen years. Scientists working for Kinsey reported data which led to the conclusion that people are capable of sexual stimulation from birth. Furthermore, Kinsey's method of researching sexuality differs significantly from today's methods. Kinsey would watch his research subjects engage in sexual intercourse, sometimes engaging with his subjects as well. He would also encourage his research team to do the same, and encouraged them to engage in intercourse with him, too.
These books laid the groundwork for Masters and Johnson's life work. A study called Human Sexual Response in 1966 revealed the nature and scope of the sexual practices of young Americans.
The Masters and Johnson research team, composed of William H. Masters and Virginia E. Johnson, pioneered research into the nature of human sexual response and the diagnosis and treatment of sexual disorders and dysfunctions from 1957 until the 1990s
The work of Masters and Johnson began in the Department of Obstetrics and Gynecology at Washington University in St. Louis and was continued at the independent not-for-profit research institution they founded in St. Louis in 1964, originally called the Reproductive Biology Research Foundation and renamed the Masters and Johnson Institute in 1978.
In the initial phase of Masters and Johnson's studies, from 1957 until 1965, they recorded some of the first laboratory data on the anatomy and physiology of human sexual response based on direct observation of 382 women and 312 men in what they conservatively estimated to be "10,000 complete cycles of sexual response". Their findings, particularly on the nature of female sexual arousal (for example, describing the mechanisms of vaginal lubrication and debunking the earlier widely held notion that vaginal lubrication originated from the cervix) and orgasm (showing that the physiology of orgasmic response was identical whether stimulation was clitoral or vaginal, and proving that some women were capable of being multiorgasmic), dispelled many long-standing misconceptions.
They jointly wrote two classic texts in the field, Human Sexual Response and Human Sexual Inadequacy, published in 1966 and 1970, respectively. Both of these books were best-sellers and were translated into more than thirty languages. The team has been inducted into the St. Louis Walk of Fame.
Erotic novels
In the United States in the years 1959 through 1966, bans on three books with explicit erotic content were challenged and overturned. They were Lady Chatterley's Lover by D.H.Lawrence, Tropic of cancer by Henry Miller and Fanny Hill by John Cleland.
Prior to this time, a patchwork of regulations (as well as local customs and vigilante actions) governed what could and could not be published. For example, the United States Customs Service banned James Joyce's Ulysses by refusing to allow it to be imported into the United States. The Roman Catholic Church's Index Librorum Prohibitorum carried great weight among Catholics and amounted to an effective and instant boycott of any book appearing on it. Boston's Watch and Ward Society, a largely Protestant creation inspired by Anthony Comstock, made "banned in Boston" a national by-word.
Only books primarily appealing to "prurient interest" could be banned. In a famous phrase, the court said that obscenity is "utterly without redeeming social importance"—meaning that, conversely, any work with redeeming social importance was not obscene, even if it contained isolated passages that could "deprave and corrupt" some readers. This decision was especially significant, because, of the three books mentioned, Fanny Hill has by far the largest measure of content that seems to appeal to prurient interest, and the smallest measures of literary merit and "redeeming social importance". Whereas an expurgated version of Lady Chatterley's Lover had actually once been published, no expurgated version of Fanny Hill had ever been. By permitting the publication of Fanny Hill, the U.S. Supreme Court set the bar for any ban so high that Rembar himself called the 1966 decision "the end of obscenity".
Nonfiction sex manuals
The court decisions that legalised the publication of Fanny Hill had an even more important effect: freed from fears of legal action, nonfiction works about sex and sexuality started to appear more often.
In 1962, Helen Gurley Brown published Sex and the Single Girclass="underline" The Unmarried Woman's Guide to Men, Careers, the Apartment, Diet, Fashion, Money and Men. The title itself would have been unthinkable a decade earlier. (In 1965 she went on to transform Cosmopolitan magazine into a life manual for young career women.])
In 1969 Joan Garrity, identifying herself only as "J.", published The Way to Become the Sensuous Woman, with information on exercises to improve the dexterity of one's tongue and how to have anal sex.
The same year saw the appearance of Dr. David Reuben's book Everything You Always Wanted to Know About Sex* (*But Were Afraid to Ask). Despite the dignity of Reuben's medical credentials, this book was light-hearted in tone.
In 1970 the Boston Women's Health Collective published Women and Their Bodies (which became far better known a year later under its subsequent title Our Bodies, Ourselves). Not an erotic treatise or sex manual, the book nevertheless included frank descriptions of sexuality, and contained illustrations that could have caused legal problems just a few years earlier.
Alex Comfort's The Joy of Sex: A Gourmet Guide to Love Making appeared in 1972. In later editions though, Comfort's libertinism was tamed as a response to AIDS.
In 1975 Will McBride's Zeig Mal! (Show Me!), written with psychologist Helga Fleichhauer-Hardt for children and their parents, appeared in bookstores on both sides of the Atlantic. Appreciated by many parents for its frank depiction of pre-adolescents discovering and exploring their sexuality, it scandalised others and eventually it was pulled from circulation in the United States and some other countries. It was followed up in 1989 by Zeig Mal Mehr! ("Show Me More!").
These books had a number of things in common. They were factual and, in fact, educational. They were available to a mainstream readership. They were stacked high on the tables of discount bookstores, they were book club selections, and their authors were guests on late-night talk shows. People were seen reading them in public.
In a respectable petty bourgeois middle-class home, Playboy magazine and Fanny Hill might be present but would usually be kept out of sight. But at least some of these books might well be on the coffee table. Most important, all of these books acknowledged and celebrated the conscious cultivation of erotic pleasure.
The contribution of such books to the sexual revolution cannot be overstated. Earlier books such as What Every Girl Should Know (Margaret Sanger, 1920) and A Marriage Manual (Hannah and Abraham Stone, 1939) had broken the silence in which many people, women in particular, had grown up in.
