This sounds like some kind of non-STD dermatitis. You could indeed be sharing your wife's yeast infection; or perhaps tinea (jock itch). Either of those should clear up with one of the OTC antifungal creams designed for jock itch or athlete's foot. If not, see a healthcare provider, such as a dermatologist. Do not use any steroid creams like hydrocortisone.

I promise I wont do this again, but I took your advice and asked my doctor what test he ran. He said he ran a urinalysis with microscope. As there was no abnormal white cells, nothing in the culture, and no symptoms, he said you do not have an STD. Does this make sense as my exposure was only oral. Sorry, I have an anniversary coming up and I want to enjoy.

Thank you so much -- you provide a great service. Also, the crew you trained at your last clinic is excellent as well. Can I make a donation to your choice of charity?
