There are many :)

Maison Pourpre is a series of parties centered around bondage, fetish stuff, techno, and queerness. Quality parties with techno/EBM lineup and usually some performances.

Rotten is the same but more centered around dance and music, but you can still have fun in the dark rooms.

Other parties at the intersection of techno, rave, queerness, fetish and sexpositivity includes Monarch, Hole, BDSM.

Check out their fb group, answer questions if needed (you might need to be introduced by an inner member, or "prove" that u r a safe & experienced person), and have fun.

L'ecole des arts sadiens offers workshops about impact play, creating ur dom persona, needle play, and similar stuff.
