Hello, Masturbation is safe, natural, normal and never unhealthy. You can continue masturbation thrice or four times a week if you are healthy enough and you have enough stamina. Excessive masturbation (like every day or more than 7 times a week) can lead to mental and physical stress which could further lead to anxiety and possibly stress disorder and further depression. So limit masturbation to thrice a week. Therefore I suggest consulting a skin specialist for physical examination, diagnosis and treatment. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. K. V. Anand, Psychologist
