It might not matter to him but they're doing something which is very sexual privately and not for any medical purposes. So that's not really fair. It's like cheating on your partner saying that you did not feel anything it just you put your dick inside someone else. But your heart belongs to your partner.

Look the seme can do whatever the fuck they want but don't act so possessive when you yourself can fall so low. That's my only point. And regarding yaoi these are one of the common archetypes and I know that. I am just sharing my opinion. And yes I know it's a different world that we are arguing about but the characters are somehow portraying people from everyday lives thou it might seem a but exaggerated.

I really think it depends on the mindset. I dont think their "realtionship" has romance involved. It's kinda like obsession and manipulation. So I wouldnt call it cheating because the "relationship" is a toxic illusion that honestly doesn't have much to do with actual LOVE. But if this was more of a normal lovey dovey romance I might catergorize that as. A form cheating.But I think we all know this won't be a normal "love" story
So fingering a guy's ass is not considered cheating?
