I am over 50, married wtih children. I used to masturbate since I was 11 or 12 and I haven’t completely stopped since. I even masturbate in the presence of my wife in bed after sexual intercourse with her. At times I do it quite often but at times rarely. Lately, I have been doing it 2 or 3 times a week. Is it harmful and what are the most immediate side efffects? I remember reading somewhere occasional masturbation is quite normal and does not have any bad effects on our health! Kindly explain.
