Hi!
Hi! It's insane how similar our story is. When I was a child, I experienced a non contact COCSA at 3, which is exposed to a porn by my 2 neighborhood. My innocence got stolen away but I don't hold any resentment towards my abuser. It feel weird to call my 2 neighborhood an 'abuser', since they probably didn't know any better. And when I was 7 or 10 years old, I got groomed and had a sexual contact with an older men. These actions blurred most of the line between what was right and wrong. So I kind of normalize these actions. I also had a lack of cognitive and suffered from emotional and verbal abuse from my parents.
When I was 11, I saw this dry hump actions in some movie or video, and at that time I thought it was normal or it wasn't wrong or it wasn't a sex. So I decided to do it to my 2 years old brother for playful and experimenting purpose, and I never have any sexual intent. I never knew it was wrong or it was sexual contact. When I grew older I realized that my actions back then was borderline abusive, and that's where I fell into a deep guilt and shame. I carried this painful guilt and shame all to myself, years and years later. I never opened up or reach out to anyone, even I couldn't reach out to my friends or my girlfriend. My shame constantly told me that I don't deserve peace and help because I'm an abuser, and unfortunately I believed my shame lies.
But after I stepped into the young adult age, I realized that what I did was a mistake, a one off mistake, and my child self didn't know any better and was an abused child. This encourage me to work on myself, distinguish shame, counselling, and etc. It was worth it. I haven't talk about this to my brother, just in case he is not ready about it. I'm currently healing and working on myself with my therapist and support group.
You're not alone with this. Please work on yourself or talk to counsellor, and if you can, reach out. You were a child that doesn't know any better and is just copying what you've just saw. Work on yourself first. Your cousin may or may not remember it but it'll come out. If your cousin brings it up, take that as an opportunity to apologize and make amend. Peace n' love
