Is this rape?

So yesterday I was with this guy and we have a long past ... we used to date but right now we aren't. Well we decided to start having sex and I was okay with it. But in the car I was throwing shade and saying that I was really tired. (Trying to throw shade that I didn't want to do anything.) but then when we got inside I kinda knew that it was going to happen , so I was in my underwear and a shirt and he was just in his underwear. And we laied down and starting kissing and then eventually we started fucking , and I didn't really say no ... (even tho I really wanted to) , so I told him that it hurt to try and get him to stop and he did. But then he just started going again. And I kept saying I was tired and then he wanted me to ride him. And I was like "no I don't really want to , I'm not good at it." (Because it's my first time doing that) and he said "come on" and grabbed me so that I was in position to ride him. And I did it ... and then we fucked some more even tho I really didn't want to..... is this rape ? Idk because I didn't fight back.
