For some reason, I feel like people might come at me for this, so I'd like to specify this is purely guesswork.
Wilbur- dominating, particularly care-takerish.
George- teasing, and denial of pleasure.
Dream- Public play, risky places and times.
Sapnap- teasing, denial of pleasure.
Karl Jacobs- praising (giving and received, depending on the day) and body warship.
Awesamdude- dominating, specifically care-takerish.
BBH- Knife-play, bondage (mostly spread bars)
Jack Manifold- also no. He feels too young to do this for idk.
