is this rape

I was on drugs at the time, and someone had stolen something from me so this guy said if I went to a hotel with him (where the person who had stolen my phone was) that he would get it back for me, so I went with him and we got a room. we were also with someone else. for about an hour we talked in the bathroom and he gave me a lot of drugs and he told me about his shitty life and all the bad shit that had happened to him and I felt really bad for him. When we got out of the bathroom we went to the bed and we were kissing and he told the other guy to go wait in the washroom until he said to come out. I kept telling him I didn't want to have sex with him but he kept asking and kissing and grinding and cohersing me so eventually i just said yes, even though I really didn't want to, and I knew I would regret It. after he started I really wanted to tell him to stop but I didnt. I couldn't even make a sound. he was so rough and choked me and I'll never forget the sound of the bed banging against the wall. eventually he realized I wasn't aroused and wet enough to continue so about 30 minutes later he stopped. I still regret not saying no, or telling the guy inside the bathroom to come out. is this rape? or am I just stupid for not saying no after or telling him to stop?
