i have had unprotected sex about a month back.... n as of 2 weeks ago i have been feeling a lil itch that comes and goes........ now i have read everyting on STD n its symptoms but i have not experience any symptoms like burning urination for example ......... i should also note i got some extra foreskin dat surround my penis when not erected ........... so im guessing its a yeast infection of some kind ?
