pregnant sex, help

So I haven't really had a sex drive my whole pregnancy, when me and my SO do decide to have sex it hurts so bad when he puts it in...and by no means is he "packing" down there. I've literally never been in so much pain even when he tries to finger me. It's like I closed myself up 😳😩 before him I had multiple partners they always said I was tight but it wouldn't hurt me? I'm now 35 weeks and I can't have sex. I really can't. It hurts too bad. Is this normal?!
