I messed up bad as a kid and I don’t know what to do but I caused this myself 🤦🏾

When I was a kid I had a friend who lived in my neighborhood and he would come to my house and play, when a I was younger I was exposed to porn and things happened to me that shouldn’t have happened but we will get into that later. One day when I was at 6 or 7 we were at my houseq and we were talking about a girl we both found attractive as a kid and me knowing the things I should’ve had known I said “We should get her to give us head” and us being so young he asked what is head and I proceeded to show him and pulled his pants down and put his penis in my mouth for about a second and he did the same to me it k I found out that that 2 of my close friends know him very well, one is his cousin and the other knows his from going to school together as a kid. This has been really scaring me because I know I really fucked up bad and I have been thinking that he if he finds out that they know he can tell them and they could either ruin my whole reputation or either try to do something to me. These things are very possible to happen because he is now in the streets and is in juvenile detention and I don’t know when he is getting out and I’m scared for when he does. I honestly wouldn’t be shocked if he would wanna do things to me. I just wish I had a better mindset and wasn’t so stupid back then all I had to do was explain how it goes instead of actually demonstrating on each other 🤦🏾
