See like the thing is Jon would use a Dom/Sub relationship as self harm especially with his mindset in later seasons that he’s a monster. Which is why Elias is on the top of the list he would choose, because he would not curb that intent at all. Also season three Tim would work too for this idea. Peter is also uniquely suited here too, and he’d probably feed off it, meal and a show you see?
Just Jon trying to punish himself and using this framework to do so.
