So this happened last year and I have no clue what to do and if it’s even rape

I was pretty drunk had trouble walking and talking and the guy wasn’t drunk at all as I snuck my own liquor at an event that didn’t allow alcohol, anyways we went to a quite place and I remember leading him on so we were making out and then I asked if he wanted sex so we did it for a bit but it started hurting and I told him to stop a couple of times and loud as well I made many excuses when he didn’t stop I said stop we don’t have a condom or stop my parents are expecting me and he said no don’t worry you won’t get pregnant and kept going. At this point I was in pain and I guess I froze because I let him continue until he was done. I felt numb and couldn’t move a muscle. He finally was done and left me there. Now I’m questioning if it is rape because I asked for sex and I was leading him on I keep on thinking I brought this upon myself and I don’t know what to do now because I keep on thinking about it and ptsd I flinch when people touch me or loud noises please comment back so I can see what y’all think because it has been really bothering me
