Personally? Not really. But as far as fanfiction is concerned… oh man.
The first two that come to mind are collaring and praise. (Collaring is a fairly recent thing, thank you Fell Papyrus (((and all you enablers out there)))). I’d probably also throw voyeurism, and……. cuddling? I just really love cuddling. I don’t care if it’s not a kink.
