Yeah, the Eagle was bad. Very picky guys. A lot of little groups. This Sunday Naked Cruising at Dirty Dicks and Sex On Sunday at Club Church (both 1600-2000). The first usually ends before 8 pm. The latter is packed with action and the techno music brings you in the mood. And their dark room is darker than the Eagle. Though the one at Dirty Dicks is even darker.
I dunno what happened to real darkrooms, als long as you can see a little bit, people are picky, only in real dark a dick is a dick and a hole is hole and it depends om your skills. I remember Bölke in Enschede had one, but that is ages ago and that sauna and club no longer exists.
