I dont think its unrealistic. They stopped because Ash realised he had done something he previously believed Karlyle was uncomfortable with, so he apologised and said it was because he felt out of control.
Karlyle felt overwhelmed in a way that wasn't necessarily good and he needed to process it, so, he walked away from it. That was after though, not really in the middle of it cause he already finished, so maybe you're referring to a different scene.
I thinks thats pretty normal? Sex can be a weird and overwhelming and complex thing! I just wish they would talk to eachother about it. Like Ash is very clearly going through something, and Lyle internalizes a lot of thoughts he should express.
realest reply on here tbh
Well you're right of course but this hasnt happened for the first time and it's frustrating me. It annoys me how he walk away whenever something goes wrong
Bruh I don't get anything why do they always stop midway through Sex? And then have an Argument. That's so unrealistic I cant anymore
