Cut feeling & outer pain on Labia

I've had the same partner for 8 years. Idk if pregnancy has triggered this but i get this horrible amount of pain like if i had small paper cuts all over my labia down to the entrance of the vagina. You cant see nothing at all. I don't have a issue lubricating for sex, and when we do have sex it almost feels like pins and needles inside. We can go a week without sex & it still hurts. My obgyn asked me if i ever suffered a trauma. If I've ever been raped or been physically abused by my husband. She said it could be a mind thing since she seen NOTHING wrong! Idk what to think because i have never had this issue ever! Anybody had this happen to you? If so what was the remedy & diagnosis?
