Help :/

For awhile now when so and I have sex I struggle ALOT to get 'wet'. We still end up doing it with or without lub, at the end after I pee it burns like hell down there for me! And then the next day or two it's so painful and uncomfortable for me to have sex, sometimes it hurts so bad that I won't even let him touch me and I end up just playing with him till he cums. Does anyone know why? I'm tired of this already honestly
