Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Such doubts could come to anyone. Nothing to worry. Masturbation is natural and habit is normal. Masturbation alone cannot deteriorate your health. But anxiety associated with masturbation can affect your health. Masturbation once a day when you are physically healthy is said to having no health issues. In your condition there is nothing wrong in masturbating if you are physically fit.
