This is the last time I will ask this, I just need clarification again because my anxiety about it is getting worse

So about maybe 1 and a half to 2 years ago I started reading....provocative manga online, basically porn. These included two males because thats what I'm into. But it never occurred to me that some of the characters in the manga could have been underage. And in some mangas they make the characters look young. I'm really panicking about this now incase the police find out and I get arrested or something because they might have been underage. I need to know if i will get into trouble for this or not. If anything were to have happened it would have happened a while ago right?

And yes I know I have already made a post on this but I didn't get a lot of answers and my anxiety over it has just got worse if anything.

Btw I never downloaded the images or anything I just read the manga on my phone. I realised how this content is making me react lately in terms of anxiety so I downloaded a content blocker and blocked all adult websites from my browser so that I cannot access them unless I unblock it.

Please help me settle this storm that's in my chest right now. Am I overreacting and this is all nothing to worry about?
