Painful sex :/

Hey guys so, my husband and I have been married for 2 months and cant seem to have sex. We were both virgins when we got married and wedding night was our first time. Hes very big and I'm very small so idk if that could cause it, the pain is just mostly like a pressure pain. Idk if that's normal, If you guys have any tips or advice please let me know ❤❤
