Overview
In gay culture, a bear is a larger and often hairier man who projects an image of rugged masculinity.
The bear concept can function as an identity or an affiliation, and there is ongoing debate in bear communities about what constitutes a bear. Some bears place importance on presenting a clear masculine image and may disdain or shun men who exhibit effeminacy, while others consider acceptance and inclusivity of all behavioral types to be an important value of the community.
History
In the mid-1980s, gay men in the San Francisco Bay Area who called themselves "bears" met informally at Bear Hug (sex) parties and via the newly emerging Internet. The term bear was popularized by Richard Bulger, who, along with his then partner Chris Nelson (1960–2006), founded Bear Magazine in 1987. George Mazzei wrote an article for The Advocate in 1979 called "Who's Who in the Zoo?", that characterized gay men as seven types of animals, including bears.
