In the late 1940s and early 1950s, [[Alfred&nbsp;C.&nbsp;Kinsey]] published two surveys of modern sexual behavior. In 1948 Kinsey published the book ''[[Kinsey Reports|Sexual Behavior in the Human Male]]''. He followed this five years later with ''[[Kinsey Reports|Sexual Behavior in the Human Female]]''. These books began a revolution in social awareness of, and public attention given to, human sexuality.

Kinsey based his findings in both these books on interviews that he and his team of researchers conducted with thousands of Americans, beginning in the 1930s.<ref name=":1">{{Cite book |last=Gathorne-Hardy |first=Jonathan |title=Sex the Measure of All Things: A Life of Alfred C. Kinsey |publisher=Indian University Press |year=2000 |isbn=0253337348}}</ref> The interviews were extensive and could last for several hours; they were supplemented by diaries and other documents that the interviewees were willing to have copied, and sometimes film of them masturbation or having sex with others, if they volunteered and it was practical.<ref name=":1" /> Kinsey found in the course of these interviews that many sexual behaviors which had previously been seen as marginal or "abnormal" were in fact more common than previously recognized and were part of the normal spectrum of human sexual behavior; for instance, he is the source of the widely quoted statistic that 4% of the male population is primarily homosexual.<ref name=":1" /> He advocated using this information to reform sex-related laws, which at the time were often draconian (for example two men having consensual sex in private [[Lawrence v. Texas|was considered a crime]]).

Kinsey's books became bestsellers when published, and laid the groundwork for researchers [[Masters and Johnson|William H. Masters and Virginia E. Johnson]] to study the nature and scope of sexual practices among young Americans. Their books, ''Human Sexual Response'' and ''Human Sexual Inadequacy'', published in 1966 and 1970 respectively, were also best-sellers, and are now considered classic texts in the field.
