I was talking with a friend about Saturnalia, where slaves and masters would exchange their roles, and randomly wondered if some modern day BDSM couples did that too. He just rolled with a "oh yeah I know a few but they're a minority" and gave a link I won't visit to a dedicated forum. The human mind amazes me.

I think I have a tendency to DO that more than have it happen lol

The mind is fascinating
I'd love to explore it someday
