Sex

In 1948, Alfred Kinsey published the Kinsey Report on the Sexual Behavior in the Human Male.

Kinsey claimed to have discovered that American men had a wide variety of sexual experiences. Many engaged regularly in pre marital and extra marital sex, enjoyed masturbating, and that homosexual experience was relatively widespread.  The book became a runaway best seller, despite its dry, academic style, and sparked a national debate over sexuality in the U.S.
