If you are experiencing red spots on your penis, it could be a sign of balanitis, which is a fungal infection. Maintaining good hygiene, especially after sexual activity, can help prevent the symptoms from recurring. You may consider using clotrimazole (Canesten) cream to treat the infection. Avoid using harsh soaps and opt for a gentle cleanser to prevent irritation. If the symptoms worsen or persist, it is advisable to consult a pharmacist for further guidance.
