question: HI,I have got married 2 years back , Me and my wife have had sex lot of times. But of late my penis starts to shrink even before I could ejaculate in her vagina.  We are trying desperately for a kid and am worried. Did my semen analysis about 6 months back and it was normal as per the report. I do masturbate every day, could that be the reason. Can you please help me with a way out since am feeling that am not able to satisfy her and sacred a lot.
