not sure if you're still checking responses............you may have vulvodynia..........look up on internet for symptoms.
vulvodynia can cause the pain you explain
good luck
There are many causes of pain during intercourse. That's really beyond my expertise. However, yeast infections cause rashes and discharges, not just pain. I think you need to ask your gynecologist either for an opinion or a referral to look into this. Meantime, I suggest lubrication during intercourse.
Best.
