I was sexually abused by my best friend when we were 10 years old.

I (24,m) was sexual abused by my best friend at the time we were 10 years old. I was in 3rd grade and had to repeat that grade, so i lost a lot of contact to my friends. I stayed in contact with one friend, the perpetrator, and our friendship grew a lot. When i was at his home he showed me gay porn, this was the first time i came into contact with the topic of sex outside of sex ed class. I wasn't really interrested in it and, nothing more happened that day, but in retrospect I think, the friend was maybe kind of testing the waters. Some weeks later, we were at my place, where the abuse happened. I lived in a multi appartment house, and my mother had rented one appartment two sories down of our main appartment, so my father could move his office down there, we could have a guest room for family menbers that came to visit. I also had a model train down there, and me and the friend spend a lot of time there and played with the train. One day, in the winter time we decided to go tobogganing at a nearby hill. On the way to the hill, and on the way back, my friend talked me into trying out the things we saw in the porn video with him. First i said no to this, as i was only 10 and not interested in this kind of stuff, but he told me this kind of actions are normel for friends, and eventually i said yes. Back at my place, he still tried to talk me into it, and i remember that i didn't wanted to do these things, but was scared to loose him as my friend. Because at that time he was the only one of my old friends i had stayed in contact with. I remember that we were kissing, dry hummping, and me on top of him rubbing our private parts together. But the friend wanted to also try out sex with me. So he talked me into oral sex. After that he treid to talk me into letting him have anal sex with me. He wanted that i take a shower and clean myself up for this, but luckily I never said yes and after the 3rd time of trying to convince me he accepted that somehow. But he wanted oral sex again in exchange. To that i said yes, so he wouldn't be and at me. But i remember that i backed off of him at first to the edge of the bed and to the corner of the wall and sometimes still feel the cold wallpapper touching my back. I remember feeling very confused by all of this, and still to this day 15 years later, i am scared of intimacy with other people and get panic attacts even by just laying in bed with someone or cuddling half naked. I also felt a lot of guilt, because i wasn't forced to to these things and said yes. But today I know better, that i was child , didn't really know what was happening and that he abused my trust and lack of knowledge. I hope i will get better soon, and maybe heal from this. I also hope all the best to all of you survivors out there. What ever happened, it was not our fault.
