Hi, Thanks for posting in HCM. I understand your concern. Masturbation when done properly with adequate spacing is normal and physiological phenomenon. It doesn t affect health in any way as you are thinking. It doesn t cause physical weakness, decrease in penis size, premature ejaculation, decrease in sexual performance or fertility. Since it is a voluntary act, decreasing its frequency can be achieved by one s own will power. If you continue to do it once a week or thrice in a month, it should be alright. Kindly indulge yourself in certain amount of time consuming work, physical exercise or workouts and meditation to keep away from feeling to masturbate. Also, kindly note that size or length of penis has nothing to do with sexual performance or fertility. Gradually, you should be able to gain control and be confident in life. Hope the information provided would be helpful. All the best. Regards, Dr. Ashakiran.S., MBBS., MD.
