Itching and fungal infections around the penis can be caused by sweating, moisture, tight underwear, not drying off well after bathing, diabetes, or skin irritation. The skin may turn red, feel itchy or uncomfortable, or have a mild burning feeling. Most mild fungal infections get better with good hygiene and the right treatment, but similar symptoms can also be caused by allergies or bacterial infections. Only take medicine or start treatment if your doctor recommends it. It is important to keep the area clean and dry. Wear loose cotton underwear, avoid tight clothes, and change your undergarments regularly. Try not to use scented soaps or random creams, as some products can make irritation worse. Avoid scratching, since this can make redness and infection worse. Depending on the cause and how severe it is, your doctor may suggest antifungal creams or tablets. Consult a doctor if you notice swelling, pus, pain when urinating, sores, fever, or if the infection keeps coming back.
