I see your 'Cas would be gentle with Sam in bed' and I understand it but I have a counter offer
Cas who doesn't really understand the limitations of the human body so he just goes off a 'if he keeps moaning then it must be okay' logic plus it feels good for him so he assumes it must feel good for Sam too (again, he has poor understand of these things) vs Sam who doesn't care if he fucking breaks as long as it's by Cas' hands because he's just so touch starved that anything feels good so he moans at literally everything and his body hates him for it the morning after but he doesn't care
