Was I sexually abused?

So when I was 12, I started dating this guy. At first things were great. They he started asking for pictures. If I didn’t send any, he would get pissed off and threaten to break up with me and tell me I didn’t love him. He would also make me feel like everything was my fault. He kept asking for more and more, and I was too scared to say no. One day, he put his penis in my butt without asking or telling me. I shoved him off quickly. He kept trying to get me to do things, and he would sometimes force himself on me. He even hit me once. I don’t know if this qualifies as sexual assault. He would threaten things that meant a lot to me. He would tell me that if I didn’t do this, I didn’t truly love him (and I did at the time). I always told him that it was important to me that he knew this. Idk what this was, but is been two years and I’m still suffering the effects. I also know that he mentally and emotionally abused me, but did he sexually abuse me as well?
