Bored and miserable so here are my Jon x Damian headcanons. (Some of them are little bit spicy and some of them are sad so be warned)
Damian was 19/20 and Jon 22 when they started dating.
They call each other 'bro', 'dude' and 'man' a lot because the habits stick around.
Jon has to wear his wedding ring on a necklace because he kept losing it.
Jon can be toxic when it comes to privacy. He has always been extremely worried about Damian. This only got worse once they became a couple. Far too often, he listens in on what Damian is doing, where he is, and who he’s talking to. He knows that Damian isn't a fan of this, so he tries to stop himself, but sometimes it happens anyway.
Damian is demisexual, and only had a few sexual experiences before Jon, (all of them with women) and he kinda checked out completely during all of them. That's also why he and Jon didn't do anything beyond making out for nine months. (Jon our strongest soldier.)
Damian is bad at communicating when he wants physical affection, so he sometimes just stares Jon down as if he is expecting him to mind read. (With time, he got better with it)
Because super hearing sucks, Damian had custom noise canceling headphones made that Jon can wear while sleeping, during panic attacks or Sensory overloads.
There isn't much Jon can do when Damian is going through a depressive episode. Unfortunately, these are situations that often simply have to run their course. So, Jon at least gets him out of bed and onto the couch, puts on a movie, and orders food. Then they cuddle on the sofa for the rest of the day.
Jon is openly Bisexual and Damian doesn't label himself.
Jon ALWAYS notices when something is wrong with Damian, especially when they have physical contact. He can detect every muscle tension, every change of his heartbeat or breathing, every slightest change in Damian's body.
Jon is one of the only few people who know that Damian has dimples when he smiles.
Damian has sketchbooks filled with sketches of Jon and some of them are spicy.
Jon is learning Arabic for Damian.
Jon is more of a top, but for Damian he’d switch. But Damian can tell that Jon enjoys topping more so he gives him what he wants.
Jon is a biter in bed.
Damian sometimes draws on Jon's back. (he got the idea from Pinterest but he would be denying that with his life)
Whenever Jon is off-world for a mission, Damian gets so anxious he has to move back into the manor or stays with the Kent's until he returns. (Vulcano trauma lol.)
