Chastity Gathering or Getaway?

I was reading a fictional story on It focuses on a guy sent to a weekend getaway where every man is locked up. It’s an enjoyable bit of fiction, but it made me curious whether something like this happens in reality, or could happen? Clearly, there’s plenty that is purely fictional and hard to replicate, yet I know BD/SM weekends exist. Has anyone attended one before? I’d rather not have too much BD/SM flair; more fem/dom dynamics or even a simpler chastity setup (Ha!). Basically, I’m imagining gathering with others who share similar interests in some way, whether we’re dressed normally or perhaps wearing something slightly kinkier. A weekend observing chaste husbands serving their keyholders would be quite enjoyable. Perhaps there’s a spa venue that could host pampered ladies while instructing the locked men on how to serve them better…
