Red marks on the glans of the penis, along with itching, are commonly seen in a condition called balanitis, which means inflammation of the head of the penis. The most common causes include fungal infection (such as yeast), poor hygiene, excessive moisture, or irritation from soaps, detergents, or tight clothing. Sometimes it may also be related to bacterial infection or sexually transmitted infections, especially if there has been unprotected sexual contact. You should keep the area clean by gently washing it with plain water and thoroughly drying it. Avoid using scented soaps, antiseptics, or any over-the-counter creams without medical advice, as they may worsen irritation. Wear loose cotton underwear and avoid sexual activity until the condition improves. Please consult a doctor or dermatologist for proper examination and treatment. You may need antifungal or other prescribed creams depending on the cause. If there is pain, discharge, or worsening redness, seek medical care promptly.

Fungal infections in the groin area are common and often occur due to excess sweating, heat, friction, or moisture trapped in skin folds. This condition can cause itching, redness, and sometimes a ring-shaped rash on the inner thighs. Keep the affected area clean and dry. Wash it gently once or twice daily and dry it thoroughly, especially after bathing or sweating. Wear loose-fitting cotton underwear and avoid tight clothing, as it can trap moisture and worsen the infection. Change clothes daily and do not share towels or personal items with others. You may use an over-the-counter antifungal cream, such as clotrimazole or terbinafine, twice daily for 2 to 4 weeks. Continue applying it for at least 1 week after the rash improves to prevent recurrence. Avoid using steroid-based creams, as they may worsen fungal infections. Do not scratch the affected area to prevent the spread of the infection. If there is no improvement within 1 to 2 weeks, or if the infection spreads, please consult a doctor for further evaluation and treatment.
