yea so basically i have this small white ring on the side of my penis head... it doesn't seam to be an std or look anything like any of the common std. i have had unprotected sex one time several months ago. and besides that i have a partner whom isnt sharing the bed with anyone but me. I have none of the common std symptoms. Its really hot and humid where i work and i was thinking its some type of fungi almost looks like ring worm but its white and not red. i have had this for almost 2 weeks now, it doesnt hurt or itch bairly and have been putting hydrocortozon cream on it.. i should really see a doctor, can anyone here give me there opinion.
