I think my boyfriend likes hurting me sexually

My boyfriend has a big dick probably the biggest I’ve been with so it hurts sometimes when he goes deep in me. I sometimes have to tell him to slow down and that it hurts and I feel like it turns him on that he hurts me or something . If I tell him to go gentle he says something like , “is it too big for you” like he’s dirty talking and I say yes because it is . Is that weird or normal
