Is AUTHOR wrong in the post ? POST : This happened a few years ago but still haunts me over who was the asshole in this situation, if anyone. Throw away because...subject matter.

So, my brother and I were both college students at the time. We were back in town visiting my parents. I was feeling ill and left the dinner table early and laid down on the couch. I guess I ended up falling asleep there because I woke up in the middle of the night to the sound of my bro masturbating. Now, this was 100% unintentional. He had no idea I was there. I was on the couch in the living room and he was sitting on the floor on the other side of the living room. So I wake up, I'm confused and don't know what to do. Like...I just froze. Fucking...what are you supposed to do in that situation? So I panicked and did nothing. Well. Whatever. He finishes, goes to his room, and scurry off to my room, the end.

It was a few years ago so I don't remember the exact details but I was pissed and told him so the next day, fully expecting him to be like, "oh shit I am so sorry I fucked up I didn't mean to" BUT NO he was pissed AT ME. 

My reasoning for being mad: it's not like it was some secret that I laid down on the couch (he was there during dinner when I wasn't feeling well), didn't intend to fall asleep there, and the responsibility is his to make sure there is no one in the room when he is masturbating in a common space?! 

His reasoning for being mad: I irreparably (I dunno, maybe an exaggeration...) embarrassed him by not making him aware of my presence and waiting until he finished/left to leave.

My response to that: I had just woken up and freaked out and didn't know wtf to do. 

His response to that: I don't remember, but he definitely stood by his position that I was the one at fault here. 

For context, I am pretty sure he was in the living room because the internet was super shitty/spotty in his room and was probably watching porn or something. I certainly didn't look, and I don't think he ever specified that this was the case, but that's my assumption. 

We both wanted the other to apologize, neither would, our parents started getting pissed that we were having some mystery fight we wouldn't tell them about and ruining family time, eventually we just agreed to never speak of it again and that was that. It hasn't ever come up again in the years since and I love the fuck out of my bro, he's a great dude, and this was a weird blip on our relationship. BUT STILL he was so adamant that I was the ass in this situation and I really didn't think I was, so here I am for judgment. I've tried to represent the events and both sides fairly. So, AITA?
