Event is held in an upscale, well-maintained, sex-positive space. The Music City Jacks have been organizing well-attended group J/O-only sessions in the decades-old "Jacks" tradition for nearly 5 years. Ours is a friendly, upbeat, sex-positive vibe. We meet monthly, rotating among Saturday and Sunday afternoons, weekday evenings, and weekday lunch hours. We welcome guys* who - want to jack themselves, watch others jack, help and/or be helped, identify as bi, gay, straight, or . . . - are HIV-negative or HIV+positive, and - will adhere to our code of conduct based on long established 'Jacks' traditions. In short, our guidelines require lips above the hips, no penetration, no anal contact, and no substance use, including poppers. *Music City Jacks events are for adult cis-men (persons who were assigned male sex at birth who identify and present as men.)
