Hi:
Thanks so much for your advice. I don't know exactly which cream he is using, but at this point I suggested that he sees a dermatologist. I believe his penile rash is hives, which is one of the listed, although uncommon, allergic side effects to the Metro Gel. It's been 6 days and no Improvement. I hope he goes to seek more medical advice, I can't imagine the kind of pain and discomfort I've subjected him to. Oddly enough the Metro Gel worked on me with no side effects...
