Is this normal for me to have done when i was that young??

ok so when i was like 9 my brother had a new best friend. So i was like cool, u know like he cute. then my brother left to go shower. then we started flirting nd stuff well about 20 mins later he kissed me, then he was like ayy gurl lets hook up. nd he was 12 so,i was ok yea sure. About 10 mins after that he was grabbing my ass and vag. sayin' ″this is all mine right babe″ nd i was yea and after we hooked up i sucked his dick almost evety time ge went to my house. then i found out that he was cheating on me i broke it off so he left the other gurl nd we got back to gether and we were on nd off for almost 2 months then he went back to that other gurl so i broke it off for good. nd when i was 11 my uncle told me that he saw me sucking my bfs dick in the kitchen and i made him promise me no to tell my mom. then my brother told me he saw me nd my bf kissing in the backyard and i made him promise too.
