Is this considered rape?!

Me and my (ex) boyfriend where in bed after being at a house party and he was still very drunk. We were kissing and cuddling and he tried to instigate foreplay but I didn't want to, as I was a virgin and it didn't feel right, so I tried pulling his hand away aswell as saying "no" so he got mad and rolled over. He then saw that he upset and embarrassed me so he cuddled me and then tried to instigate foreplay again and I still didn't want to but he was insistent and I gave in.

He then put my hand on his penis and I went along with it as I was scared and anxious about upsetting him. He then asked "do you wanna have sex?" And me being anxious and scared I said "I don't mind" and he asked again and I said the same thing. He then said "we can try it and if you don't like it we can stop" so I agreed as I still was scared to say no.

We were in the doggy position and he got very rough and had seemed to forget that it was my first time as it was extremely painful and I kept grabbing and tapping his leg saying "slow down" "stop" which is what he said to do if it hurt too much but it didn't have much effect as he just grabbed my arm behind me and continued until I couldn't bare it any longer and flipped myself over to stop him. He then asked me to give him oral and he passed out during that as he was super drunk. The next day after I went home he texted me and asked me if he had raped me as he couldn't fully remember what had happened and I told him no he didn't but he was very rough and I showed him the bruises on my hips from where he held me.

This was over a year ago and it has given me bad anxiety which has stopped me from having any sexual interactions with partners.

I don't know if this was rape or not.
