I just saw a funny Dom capture a sub as slave that I had previously tried for (and missed). He's the kind of guy that seems to carry around "this is fun" vibes whereever he goes. I was very jealous of course, but I also took away a lesson.

In a different context, I was just warned against using humour in my bdsm fiction, by the publisher. He told me to remove anything funny near the beginning, "until they're already hooked on the story". And he has experience.

So maybe humour is good in real live sex but bothers people watching/reading about sex?
