Can I still go to heaven if I had unintentional gay sex before puberty?

My cousin and I were alone one night and we were bored. He tempted me to have intercourse with him. I'm a boy and so is he. It was such a situation for me that I couldn't reject, but now I am very guilty about my deed. So I had a gay intercourse with him. But we never had anal , we just rubbed our “things together”. I have done it about 6 time and masturbated 4 times with more people. I also kinda did a blow job where he put it in his month for 2 sec and one time he put his tip in my behind! It was 5 or 6 different people. This was before puberty. I’m special ed/ I have ADHD (I didn’t know better) All of them were older then me like a year older. To this day I still regret it. I was young and dumb and afraid I’m gonna go to hell. Will God forgive me?
