like I said it burns only when I touch it. Ik it's not a std cause my partner and I are completely devoted to one another. it doesnt hurt at all when walking. It's not pimple like. It more like a white crater with red Around it. I recently had a UTI and the antibiotics gave me a yeast infection. Could it be from that? Or could rough sex do this to me? if none of the above than what?!
