The Eulenspiegel Society, LSM, and the Imperial Court of New York have been the most prominent and longest-running co-sponsors. Other leather and fetish organizations in the NYC metropolitan were later invited to help, and in the 1990s GMSMA formally turned over control of LPN to a coalition of community groups representing diverse gay, lesbian, pansexual, and heterosexual orientations. LPN was founded and initially produced solely by Gay Male S/M Activists (GMSMA). Once the Gay Pride Day events had achieved a firm financial footing, LPN also benefited additional community beneficiaries ranging from the LGBT Center to the Anti-Violence Project to numerous HIV/AIDS charities. Other elements over the years have included a raffle, a silent auction, and a flea market for used leatherwear, books and magazines, and SM/fetish gear.
Early on, the focal point of the evening became a live auction of donated goods and services, with Jo Arnone, one of the founders of the Lesbian Sex Mafia (LSM), as the regular auctioneer.
