first time corn?

I have seen someone talk abt it here , that corn exposure at young age is soo wrong and no kid has to go through that. well I have been exposed to corn maybe when I was around 9 I guess? i talked abt this once here before. but I actually want to know how different types of reactions people had. I actually saw my uncle watching porn in broad day light at our house , when everybody were having a nap. I actually stared at the screen for 5 mins , and that man did not bother turning it off , he just glanced at me and back at the screen. i ran back to my room. was disgusted by him clearly. and even now I dont interact with him nor greet him at family gatherings.
anyway the thing I'm curious is abt reactions or say wt happened later. as of me i searched up 'sex' on youtube. cuz i did not knw wt else to call it. obv got nothing out of it. but yea I did feel like I have lost my innocence may be? knowing smthg explicit so soon.
