I dont know who to ask and no doctors wants to help also trigger warning

Im in a rush so sorry if its confusing or you cant read it well. So I'm in my late 20s with 3 kids and sex is painful. I refuse to have sex with my partner because of it. My doctor will not help me figure out the cause. They just tell me in a fast tone "thats for a different appointment" every single time i bring it up. I told them it's taking alot just for me to even talk about it because i don't talk about sex and dont like talking about it at all so for me to bring up sex.. there is something really wrong. They tell me they understand. I feel like they don't want to help. I was R**** twice like 8-9 years ago but i don't think that could be the cause but not sure. I am clean and so is my partner so no infection or anything. I feel like i will never know the answer and i will have to endure the pain or just not have sex all together but its that painful. What COULD be the reasons for my pain? Im trying to find a doctor thats willing to help. Im going anonymous but if you ask a question ill respond.
