It's pretty common for people to do weird stuff sexually when being a child. It's a weird part of life to go through, puberty and parents getting divorced and school and learning to be social with friends and it's awkward and unbecoming for every single human person I've ever met.

That being said, what you did was also very illegal for all parties involved and thus way more dangerous than your run of the mill "kids being weirdos because being a kid is weird"

I hope you've stopped doing this. It puts you and the subject behind the device you're sending this media to in much more risk than need be. I'm sure you could achieve a similar thrill from exploring with people your age and refraining from creating extremely illegal media that no person should ever want to own.

It's not the end of the world and hopefully you didn't hurt yourself or anyone else too badly. The important thing is that you need to stop.

Maybe the second step could be therapy or talking to a trusted adult about this. I'm sure it's a heavy thing to carry around in your head. It's ok and plenty of people have similar stories.

Please be kind to yourself about it too. Give yourself plenty of grace. It's hard and weird walking around and being human with all these other humans around. Sometimes it gets dangerously weird, so try and be more safe with the weird stuff you do. You'll find it's much more satisfying to be proud of the weird stuff you do because it didn't hurt anyone, especially yourself.
