It is important to seek medical attention for any concerns related to redness or irritation on the penis, especially in a 14-year-old. Consulting a doctor for a proper diagnosis and treatment plan is the best course of action. It is not recommended to apply any cream without a clear diagnosis, as it could potentially worsen the condition or cause further complications. If your doctor is unable to see you promptly, consider utilizing telemedicine services like Bonjour Santé or Maple for assistance.
