im afraid and alone

Idk anymore it feels like being on here is a trigger. Every time I see a minor post on the app, my intrusive thoughts go haywire and then my brain says maybe you should comment something inappropriate and i literally don't wanna fucking do that. It's the last thing I want to do. And now im scared that I commented something crude on someone's post. obviously, when I went to check there was nothing now my brain is saying "you commented and then deleted". I want to think it's something I wouldn't do, but why are the images in my head so real. Children should be safe. I feel like I need to be locked away. Someone please help me.

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?

I was in the car I suddenly noticed someone across the road, and I perceived something that looked attractive and se&ual, like exposed nice legs, and I thought, well let's look, it must be a woman. she wasn't. it was a trigger and i wasnt ready. she was wearing low cut shorts. and the thing is when i noticed how the body was too small i think it still looked someway attractive, my brain perceived that overall look as attractive or se&ual, like it "felt nice" (?) idk. it all happened very fast so i dont know a lot, but I got immediately disturbed as i noticed and perceived such a look. i dont know if i really "felt" as opposed to "perceived". I didnt have desire. I didnt want it. but was i attracted? that's a strong word, but im afraid that the brain still felt something "nice", like the overall look was attractive or nice, as an instant positive reaction <brain: "oh that looks nice"> is that normal? am i a ****phile? i wasnt ready. it was sudden as i checked, it took some time to fully process the information. if i knew from the first thing that it was a trigger as usual, in a slow manner instead of sudden noticing, i wouldn't have felt this much uncertainty and these disturbing unclear reactions, i would thought "this looks se&ual because it is exposed skin but im not attracted to it". all this time i thought that when i noticed certain body parts was because it just looked se&ual and because of ocd, after this im starting to think that i find certain looks attractive and i recognised a similarity. maybe, could it be that my brain took some time to fully process things, and because it wasn't ready it wasn't able to relocate in time what was appropriate and not? like piece of informations didn't have enough time to be fully processed so instead of coming into one clear image it was fragmented, and something attractive slipped through as a separated information from the subject...? im very distressed and depressed because of this. the final nail in the coffin for today; i want to kick the bucket.
