shitty memory.

I have seen someone talk here abt how young children shouldnt be exposed to porn. which is so damn true btw. but at some point I uh saw porn or had to see when I was around 9 maybe. its kind of messed up memory though for me. back then my uncle used to stay at our place often. this one afternoon , me and my mum were napping, i got up for water. so the thing is we had a computer in our living room. yea pretty weird place for it be. probably my dad put it there so me and my siblings wont fight over it and use it in order, but iam pretty sure he did it so my brothers wont watch dirty videos . anyway so when I went downstairs. I saw my uncle watching porn. I even remember naked people in that video. I stared at the screen for 5 mins or so idk y, and tell me y this man did not even bother turning it off or asking me to leave. he knew i was there. i quickly ran back to my mum .
idk if I can call this a traumatic memory though. but I dont interact him or even greet him and just leave the room when tht uncle is around. anyway that uncle of mine he is still unmarried. yeaa I wonder y right. I still to this day dont understand my uncle . I actually knew I was gonna take this to my grave. for obvious reasons I couldnt tell it my mum or dad. but sharing is fine I guess. had any experience like this? gosh I wish not though.
