If you enjoyed Berlin’s KitKat Club, you’re already familiar with one of the top spots for combining techno music with a sex-positive atmosphere. Here are some suggestions for other similar experiences across the regions you’re interested in:

1. Germany: Aside from KitKat in Berlin, you may want to check out Insomnia Club (also in Berlin), which offers a mixture of techno music, BDSM, and swinger-friendly nights. In Munich, Swingerclub Babylon is known for a great balance between clubbing and socializing in an erotic setting.

2. Netherlands: In Amsterdam, Club Church is a well-known place for inclusive, sex-positive events, often featuring great music and themed nights for a range of different preferences. Fun4Two in Moordrecht is another famous swingers’ club that regularly hosts techno and dance music nights, with a friendly, upscale environment.

3. Belgium: In Brussels, The Mansion is an excellent venue known for erotic parties and techno music. You might also want to explore Noxx Antwerp, which occasionally hosts sensual parties alongside electronic music events.

All of these clubs tend to balance music, freedom, and respect for boundaries. It’s also worth checking online or local listings to confirm any specific event schedules as some clubs only have these types of events on certain nights.

Have fun exploring, and enjoy the vibrant club scene across these countries!
