White substance with pain, small cuts, and burning on the head of the penis may suggest a fungal or bacterial infection and should not be ignored. Keep the area clean and dry, wash gently with water, and avoid harsh soaps or forceful cleaning, as it can worsen irritation. Do not apply random creams, as some may worsen the problem if they are not suitable. It is best to consult a doctor for proper diagnosis and treatment, which may include antifungal or other medicines.
