oh my fucking God, your sirius james relationship dynamic is sooo juicy. Fucked up queer friendships are the thing I'm DEFINITELY weird about. I think if Sirius and James ever did have sex or like, have any heat of the moment thing James would immediately draw huge boundaries around their friendship or just like temporarily terminate it. Just like, in bed still, and James is like "I think we should give each other some space" or something vague and noncommittal that basically means bye. Perhaps even the catalyst for James straightening out and winning Lily's affections.
screammm I am BARKINGGGGG Ok. Here's the thing. I fully agree James would act like this, and say shit like this, but I REALLY don't believe he'd actually be able to DO IT it. He's too obsessed with Sirius and too codependent with him to actually be away from him for that long. He also cares too much what other people think--what is the school going to say if they see the Dynamic Duo, Asshole Bullies, Kings of Hogwarts, not hanging all over each other hexing Snivilus on the lawn? It's unbearable for him to imagine.
These are kids who invented a two-way mirror so they could Wizard Skype one another during separate detentions because they simply could not bear to be apart for a few hours. Would James want to get away from Sirius to prove he's actually straight and that he didn't let his best mate suck his cock? Totally. Would he be actually able to execute a clean break? Hell noooooo he would come crawling back apologizing in like fifteen minutes pretending nothing ever happened and SIRIUS KNOWS IT!!! He knows James I Wish I Knew How To Quit You Potter is emotionally and physically incapable of enforcing any real separation between them.
And the most horrible thing about this? It means the onus of Getting Over James is entirely on Sirius's shoulders. James won't ever actually give him space, so he has to teach himself not to want James, in spite of the proximity. He has to kill the desire, kill the hope. Throw himself into loving James without wanting more from him. Which god, as a teenager?? That's so fucking hard.
All this to say, I head canon Sirius as the one taking space in order to allow James to actually date and be with Lily. THIS DEFINITELY shows up in my fic heeheh.
