What are men at swingers’ bars usually like?

Teramoto from Universe Club’s Tokyo branch will answer as well. I’ve only been there once, but rather than the wild, decadent scene I’d imagined, it felt more like a bar with a high percentage of ordinary men. Since they also charged an initiation fee, I was expecting something much crazier, so I was a little disappointed… Next time, I think I’ll go with someone who knows more interesting places (;_;)
