18+ I’m so worried I feel like I’m panicking

I’ve been dealing with a lot of anxiety and uncertainty I think I’m really struggling right now. I was in my alone time (self pleasure) and obviously like whenever you’re doing your thing you might have fantasies or whatever and that’s what came into my mind in the moment and then all of a sudden I get a flashback from a scene from pretty little liars came into my mind where Emily kisses Ali on the neck. In pilot actor who played Allison was 12 years old, which the pilot was the first episode I believe but in the rest of the season of season one she was 13 and that flashback was in season one as well after the pilot and I’m really worried that I might have self pleasure to myself to that scene even though I knew all this time that she was 13 in that scene and I don’t feel comfortable because I’m 16 and even though like it’s not too much of an age gap it’s still polished me and I’m scared to death right now, but I didn’t panic immediately because I think I somewhat kinda knew in the moment that I probably didn’t do anything bad but I am not 100% sure and then the more I thought about it, I started to panic even more and now I’m panicking even more now and I feel like a really big pedo, and I keep searching and googling and trying to check for her age to see how old she was in that scene and I’m pretty sure she was 13 but I promise I wasn’t intentionally thinking oh yeah I’m gonna self pressure myself to this scene regardlessof her age. No, I’m just afraid I probably did without even like realizing or registering the thought in my mind, but then at the same time I kind of feel like maybe I was just coexisting with a thought and now I’m scared I’m really scared guys.

So one day a couple months ago I saw some posts on threads pop up on instagram and they said I’m 17 and horny and 18 and horny or I think I even remember see a 16 year old one. I’m 20 and I remembered that when those popped up I clicked on them and I don’t know if I did it out of true attraction or out of the urge to make my anxiety go away. I feel like often times if I see something that says any number under 18 even if it has nothing to do with age it could be talking about season 17 of a tv show my mind immediately goes what?? 17??? And then I click on it to make my anxiety go away. So when I remembered all of this I downloaded the threads app because I wanted to see if I could get reassurance and see if I could rekindle how I felt in these moments. When I opened the app all I saw was posts like that but everyone claimed to be 18. The only problem is none of the girls looked 18 they looked like 14-16 so I started to panic I and worry that because I clicked on the threads in the past it popped up more and I was a pedophile for that. All of the accounts all pretty much had only fans links so at that point I was like well they have to be 18 then but now I’m worried that maybe it’s a scammer and they are using underage pictures of girls and putting them on onlyfans. Which I know is out of my control but I just feel like a Pedo and like I did something wrong. Does anyone have any advice? Or have any similar situations/ similarities with this?

TW: porn mentioned When I was younger around 18-19 or maybe younger, I stumbled across some porn labeled as 'teen'. I don't remember if I watched it or get scared away by 'teen', but I then searched for porn something like '18-teen years old', I wanted to make sure it was legal. Now I'm spiraling that I did it because I wanted to see someone younger. Or what my intentions could possibly be? It happened for once or I cannot remembered searching something similar ever again. I've always preferred bigger more masculine men, but why I did that then? I had active porn addiction since I was 9 or I'm afraid younger, watched some things that I regret watching... And now I'm 23 and don't watch it all for like 3 years, because I found out that it was unethical. When I was little I preferred BDSM porn and everyone was very mature and I did not watched anything questionable with real people, but some weird fictional stuff, but didn't like it. Now that I remember this I'm very confused and don't know how to continue living with that. I'm just done...
