Hi, I have recently noticed a spot on my tounge where there are no taste buds or at least there is no apparence of them. there looks like there could be an infected taste bud in the middle of the red tastebud-less spot but i have had no discomfort. I thought it could be geographic tounge, but i have recently ate spicy foods and experienced no discomfort. However, I have also had unprotected oral sex recently, but no fluids were exchanged and it was extremly brief.
