Just out of nowhere

So lately my boyfriend has just randomly coming up behind me and starts fucking me which at first I was confused by but now I’m just not okay with it because I like to slowly ease into sex also I don’t always want to have sex and when I tell him I’m not in the mood he just tells me that I’m hot and he wants to fuck me. Yesterday I was doing the dishes and he just got home from work and he didn’t even take his shoes off he just walked over to me and pulled my pants down and started pounding me against the sink. It hurts and I said “not now I’m busy and not in the mood” and he just responds with “you’re so hot babe I love it when you’re tight like this” I tried to move away but he had me pinned against the counter. It’s come to the point where I’m scared when I see him. A couple days ago I woke up to him penetrating me. He just pins me down and now when it happens I just freeze and I can’t move or think. I know he wants sex but I feel so helpless and I don’t know why he won’t listen to me. What do I do?
