Sexual Behavior in the Human Male

The Kinsey Reports are two books on human sexual behavior: Sexual Behavior in the Human Male (1948) and Sexual Behavior in the Human Female (1953), written by Alfred Kinsey, Wardell Pomeroy and others and published by Saunders. Kinsey was a zoologist at Indiana University and the founder of the Kinsey Institute for Research in Sex, Gender, and Reproduction (more widely known as the Kinsey Institute).

Sexual Behavior in the Human Female was based on personal interviews with approximately 6,000 women. Kinsey analyzed data for the frequency with which women participate in various types of sexual activity and looked at how factors such as age, social-economic status and religious adherence influence sexual behavior. Comparisons are made of female and male sexual activities. Kinsey's evidence suggested that women were less sexually active than men.

The publications were immediately controversial among the general public. The findings caused shock and outrage, both because they challenged conventional beliefs about sexuality and because they discussed subjects that had previously been taboo.

Kinsey's methodology used to collect data has received criticism. It has been suggested that some data in the reports could not have been obtained without collaborations with child molesters. The Kinsey Institute denies this charge, though it acknowledges that men who have had sexual experiences with children were interviewed, with Kinsey balancing what he saw as the need for their anonymity to solicit "honest answers on such taboo subjects" against the likelihood that their crimes would continue. Additionally, concerns over the sample populations used were later addressed by the Kinsey Institute. The conclusion of the Kinsey Institute was that none of Kinsey's original estimates were significantly affected by these data sources.

Parts of the Kinsey Reports regarding diversity in sexual orientations are frequently used to support the common estimate of 10% for homosexuality in the general population. However, the findings are not as absolute, and Kinsey himself avoided and disapproved of using terms like homosexual or heterosexual to describe individuals, asserting that sexuality is prone to change over time, and that sexual behavior can be understood both as physical contact as well as purely psychological phenomena (desire, sexual attraction, fantasy). Instead of three categories (heterosexual, bisexual and homosexual), a seven-point Kinsey scale system was used.
