Is there such thing as to big?

Okay so my boyfriend is 9inches sometimes 9 1/2 inches down there. He is 5’10 and I’m 5’3 I’m very small and skinny. I’m also naturally tight, I’ve had complications with previous partners with it not being able to fit and it also hitting my wall during sex and they were only 7-7 1/2! We haven’t had sex yet and I’m very scared to do it with him, I feel like its going to be to big and it’s going to hurt like hell and not be enjoyable. Also penetration alone doesn’t do it for me so I’m scared that If it’s to big it will hurt and distract me from being able to do what stimulates me during the sex! Any advice?
