Hi ... Masturbation is safe and pleasure giving procedure .... But over practicing should be restricted ... You seem to be had over practicing it since you are getting your penis sore by it. It can be done up to 3 to 4 times per week maximum.... Overmasturbation can lead some side effect according to few articles like...... Anxiety/chronic fatigue / groin discomfort /mood swings /concentration problem / study and social adaptation problem / back pain etc.... Yoga and daily exercise will be helpful... If still have doubts consult psychiatrist for further counselling session. Take care
