Dryness during/after sex

Me and my fiancé have just had sex it hurt when he put it in but I adjusted it so it was comfy. After we finished I went to the toilet as I normally do and it stung so bad I was sweating and felt weird, I was very wet whilst having sex it it seems to be afterwards it hurts. It hurts to move or sit normally, Can anyone help at all? Anyway I can stop that?
