Dear sir. I am a married man. I have two females. One of 19 year other is of 13. My wife don't want third child, what precautions we should adopt during intercourse. She starts oral pills but due to reaction milk secretion in her breasts starts and doctor advised her to discontinue the pills. Copper t was also used but bleeding problem starts, we don't want family planning. During intercourse I throw the sperm outside due to this problem I start masturbating. We use condom also but it irritates both of us and our sexual organs get irritated. How many days are safe for intercourse after mensuration cycle and also tell what will be the critical period. Please guide me in this regard so that I can live a happy marriage life.
