Oral sex

So my bf and I have had sex, various times, but recently he’s been trying to make me orgasm my rubbing my clitoris, though ya girl loves. My inner labia is longer than the outer. He’s been recently now been trying to pull my small “hood” to rub my clitoris and woman that with their labias like me know that our “hood” has been there a while, it’s protective (somehow) without it it makes our clitoris vulnerable to let’s say being supeeeer sensitive. So it hurts when he’s down there thinking I’m being pleased. It hurts a bit for 1-2 days later as well. What should I do? I don’t want him to think he’s doing wrong, but yea. idk
