Bondage demonstration at the Folsom Street Fair. A subculture of gay men , sometimes called leathermen , were among the first groups to make obvious hints of their tastes in bondage in public. Other groups, including pansexual and heterosexual BDSM enthusiasts, later followed suit. Early public displays were mainly limited to the wearing of certain fashion items, such as collars and cuffs. Over time, more explicit public displays arose. These events are few in number and highly controversial in most regions.
