Idk if I was raped...

My boyfriend and I have sex all time but this time it was different. We have consensual sex at first then went to get some food. Later he wants to go for round 2 but I didn't want to. I SAID NO MANY TIMES. But he did it anyways. But after a while I started to enjoy it but I was still saying no. I feel like I was raped but idk because ig I started to enjoy it. Idk if that really makes a differences though.

UPDATE: I talked to him about it he said he was really sorry and he would never do it again. I told him if it was ever to happen again there's no little conversation about it I'm calling the police.
