Doggy Style Pain during sex

I lost my virginity recently and my partner and I have tried different positions. Missionary gives me a little discomfort but feel great and doggy style feels fantastic but hurts like ugh. When he did it for the first time it’s like I could feel him hitting a wall, maybe my cervix. I create enough wetness so I don’t think it’s that but I don’t know what I should do to get the pain to stop especially in doggy style and riding I know is going to be even worst pain. Any help; tips or advice please?

Much appreciated ☺️
