Vagina PAINS

So I had really rough sex a couple weeks ago. My partner is very well endowed and we’ve always had trouble getting it in. A few months ago the OBGYN told me I had extra skin around my vaginal opening that hadn’t disappeared yet so she gave me some cream to help the process speed up. I thought it had worked because I can finally wear my diva cup and have sex without it being abnormally painful. The other day we had sex and it was painful again and was the roughest it’s ever been. I assumed I had torn a bit but that’s happened before. But it’s been like two weeks and it’s sooo painful. I checked and everything looks normal. When I pee or shower it hurts if the pee/water touches the area just behind my vaginal opening. Does anyone know what could be happening??? I’m going to the doctor tomorrow but I’m scared.
