Leather has been a predominantly gay male term to refer to one fetish, but it can stand for many more. Members of the gay male leather community may wear leathers such as motorcycle leathers, or may be attracted to men wearing leather. Leather and BDSM are seen as two parts of one whole. Much of the BDSM culture can be traced back to the gay male leather culture, which formalized itself out of the group of men who were soldiers returning home after World War II (1939–1945). World War II was the setting where countless homosexual men and women tasted the life among homosexual peers. Post-war, homosexual individuals congregated in larger cities such as New York, Chicago, San Francisco, and Los Angeles. They formed leather clubs and bike clubs; some were fraternal services. The establishment of Mr. Leather Contest and Mr. Drummer Contest were made around this time. This was the genesis of the gay male leather community. Many of the members were attracted to extreme forms of sexuality, for which peak expression was in the pre-AIDS 1970s. This subculture is epitomized by the "Leatherman's Handbook" by Larry Townsend, published in 1972, which describes in detail the practices and culture of gay male sadomasochists in the late 1960s and early 1970s.
