Possible infection??

So whenever I have sex, it is always painful, almost like a burning sensation inside and there’s a strong odor pretty much all the time. I thought it might be BV or another infection as I used to have recurring yeast infections but I’ve been tested by my gyno for BV, yeast, trich, and STDs and I have none of the above. Just wondering if anyone has ever experienced this or has any idea what it could possible be.
