I feel soooo guilty

i need some advice!! when i was 16, i was watching an anime and this character had abs and he was 12. i remember at the time (from what i can remember), i made a weird comment on his physique. saying things like “omg how did he become this buff haha.” and “oh im going to jail.” i even said “it’s only a 4 year difference.” like WHAT?!? just because it’s a 4 year difference, doesn’t make it okay. its WEIRD!! why would i say that? i also want to mention that i have a hard time keeping my thoughts to myself bc of my ADHD, so i tend to blurt things out. i just find it disturbing that i would have such thoughts, let alone say it out loud. i never had attraction to kids bc its immorally wrong and disgusting, but i feel no different from the ppl who would hurt children irl. I’ve tried forgive myself multiple times, but what i did is irredeemable. i feel like i am using my OCD as an excuse. i am so scared that i am a p, i want to d1e. my life is ruined.

Ive dealt with pocd for a very long time now and it gets more real as time goes on. I was watching a movie and I’ve read the books so I knew there was a kiss scene coming up.The actors and their characters are children but I was basically looking forward to the scene. Then as they were kissing, it looked kind of weird and mechanical because again the actor was technically still a child. And I let myself indulge and enjoy it, of how someone young was doing something sexual and adult like. Idk I feel like a fuckikg creep but I don’t WANT this. There was nothing intrusive about this, it’s just something creepy that I’ve done. I keep ruminating about it but still. I don’t identify myself by this mistake but it still sucks. My mind then went to children that I know, one girl and one boy, and them separately doing sexual things for the first time and navigating that and it feels like I like it but I don’t. It’s not as real as the movie scene because the fact I enjoyed the scene WAS real but it’s still stressing me out.

I think I know what honestly is what caused my OCD. I’ve never told anyone this but I have to if I want help. When I was either 10 or 11, I think 10 I was at my family’s thanksgiving dinner. Around this time I discovered porn and got addicted. I would watch porn and read erotica. Because of this I guess I wanted to experiment. I feel absolutely horrible just thinking about this but I was playing around with my little cousin, he was around 7 I think and I remember we were playing chase or hide and seek, and I grabbed him and hugged him (something I never done before), and got a boner. I did this for pleasure. That’s all I did that was sexual but I feel so horrible. I try to give myself grace as I was only 10 and didn’t know the consequences of something so disgusting. I keep thinking “what if I went farther and hurt him?”. I talk to him sometimes and he seems comfortable with me and I think he doesn’t even remember this ever happened and just thought I hugged him for some reason all those years ago. I am NOT attracted to him at all but I think this incident and remembering it when I was 14 has caused my OCD such as POCD for all these years. I am 18 now but I feel absolutely horrible. And now it’s even worse because I have been invited to his 15th birthday party in Mexico. I’m traveling all the way to another country just to be near him! Obviously I know I won’t touch him or be innopropriate with him. But what if he has felt uncomfortable with me all this time? He seems fine with me and not uncomfortable around me but still. If I feel as if I go to this trip, I am a horrible person. I don’t know what to do. Am I a horrible person for what I did and continuing to be around him? I remember reading Reddit and Quora stories of similar people who felt horrible and people told them to not feel bad as they were only children and they learned and now know that was wrong and that to not tell anyone as it could only make things extremely awkward.Please help. I know COCSA is a very serious topic that harms people and I feel like a horrible perpetrator now.
