Hello... I am 34 years old and have my fair share of intense sexual activity... always use a condom and get tested regularly. I have no stds but I do have eczema, tinea versicolor and extreme dry skin from time to time. the question I have is this... About 5 weeks ago I noticed jock itch down south as well as a couple of dry spots of skin on my penile shaft and head... with friction the dry flaky skin comes off and is bright red underneath... those same red spots have been there on and off ever since... ketoconazole and nystatin were both tried on the order of my doc and my dermatologist but neither of them scraped or swabbed to test... Any ideas on what it could be... there is no pain, itching or swelling involved. just redness.. bright red. From what I have read online it could be my eczema or dry skin but the whole cancer thing has me freaked out. the jock itch was cured with ketoconazole but neither that or the nystatin worked on the other spots... i mean it did for a bit but they came back on and off...
