Am I too tight??

When I masturbate I can comfortably fit 2 fingers in but when I try 3 fingers it starts to hurt. I’m about to get married and have sex for the first time. I am scared that I won’t be able to fit my future husbands penis all the way in, and I feel really bad about this because I don’t want to dissappoint him. He is so loving and caring and I know he won’t care even if I can’t do it, but I just want to pleasure him as much as I can.
