To start I am 31 and have been in a monogamous relationship for 11 years. about 1 year ago I had brief unprotected oral sex with a woman that i did not really know. a month later i developed a discharge from my penis and confessed all to my wife. A visit to the ER and a swab test followed. I followed up with primary care dr. and the test came back neg. for clym/gon.. I was relieved and forgot about it and recommitted to wife and family. Now a year later I have an irritation and very small pink/red spot on the tip of my penis right at the opening to the ureathera (underside) that the Dr. was convinced was yeast (Dr also did another swab that was neg. for clym/gon) and gave me fluconazole. My wife also saw her Dr. and tested negative for bacterial vaginotious and/or yeast infection. That was a week ago and the tip of my penis is still irritated and it is bothersome for my underwear to rub against it. I have spent a year rebuilding my wife's trust and don't want her to think I have done something to get an STD. What could it be other than yeast? Is it possible that i have something that took a year to develope? Please excuse any mis-spelling.
