There is a CSD party at Quälgeist that will probably feature a bit of lycra along with everything else. I would just register in advance as they fill up. Note that QG is a community owned, community-run playspace. There is no dancefloor/DJ/drugs and no phones allowed inside beyond the locker room, but there is a cute bar/social area, nice techno playing, friendly people, and two floors of very mindfully built playspaces inside to wander/watch/join/host.
Otherwise Berghain's CSD party will definitely have a ton of lycra but prepare to queue for potentially a few hours.
My favorite party is Lunchbox Candy's Ket Gala which will also have some lycra for sure, plus a darkroom, but it's not a sex/fetish party, more about the music and queer community.
