I’m petty sure SF/Folsom St. has clubs catering to that sorta thing... ;)
I’m afraid to ask but what’s a “FS/Folsom St.?”
You are probably better off not knowing... wish I didn’t. But you asked ;)...
San Francisco/Folsom Street Fair. All the gay letherboys into bondage/sadomasochism/whips and chains.
FR has threads about it from time to time. Some seriously sick pups. Makes the most ‘out there’ Brony/Furrie types tame by comparison. I guess the real difference between us and FS types is for some reason we don’t feel it needed to have parades about whatever kinks we come up with sexually.
