Is this rape and was it an abusive relationship?

I need to ask a quick question about about my past I hope nobody get triggered or upset by this but when I was 13 I had boyfriend let’s call him X we were together for a bit and he was nice however he used to tell me stuff like he had done stuff with other girls for a joke but he only said it was a joke when I started to cry he had me feel horrible and we finally decided to have sex the first time I did give consent but because of my medical history it was very painful and told him to stop and I never wanted to do it after that but I ended up doing it anyway because X used to say that if I didn’t it made him feel that he is ugly and stuff and then he would threat to cut himself so it just ended in an argument of me this saying no to him and him just saying that and when I did get out of it cause he did this to me multiple times he would cut himself right I’m front of me and saying it was all my fault sounds just gave up eventually and I never ended up fighting him off or screaming I just use to go home and cry and I’m generally confused if it was rape or not because I don’t want to say it is cause it would be horrible and offensive to say that but I am mentally scarred from my experience
