What is wrong with me?

My boyfriend and I have tried many times to have sex but it causes me a severe burning pain that brings me to tears and will last up to like an hour afterwards. We have tried lube and plenty of foreplay it's not like I'm not turned on. My PCP says it's just a normal thing the first time and my OBGYN says there's no reason to examine me if I'm still a virgin but the pain is horrific.
