I'm so nervous about my wedding night what to do?

I’m 22 years old and I am getting married in a little more than a month. I am so excited to be getting married but am very nervous about my wedding night, more than I thought I would be. We are both virgins and we have never even held hands or hugged with each other or anyone else. We don’t touch in our culture before marriage. We date for the sake of marriage and its done conservatively. I am attracted to him and we are a good match, better than with anyone else we have “dated”. We have fallen in love even with these kinds of religious limitations. We have talked about this a lot recently and I know he will be very gentle as hes promised but I am still very scared. Will it hurt a lot? Will there be a lot of blood? Will he be able to see it? Will I disappoint him? What kind of positioning would be best? I feel stupid for asking, but I can’t talk to my mother about this. Shes very conservative and never talks about this subject. My older sisters who are married also do not talk about this, neither do my married friends. My parents have hired me a bridal teacher but she doesn’t talk about this subject either. She talks more about cleanliness and religious issues. Please help! I need to be ready.
