I know "Everwood" use to be a popular medieval set of kink roleplay rooms, but I'm not sure if they are still active.
It might be worth finding 1 or 2 role playing partners who are kinky and reliable, and opening up your own room with them. Keep the role play going and let others join in.
You can probably find people into RP + kink by searching the public chat rooms for the keyword "roleplay", with the AP filter on, and the occupancy filter on.
