I m 21 and since last few months I have been masturbation a lot like almost every day or alternate days . Also I m having stomachache since 2 months and while masturbation the semen volume ejaculated is really less . So what can be the issue and how can I cure it . Since 2-3 months I have tried to control though . But still the volume ejaculted is really less. Also I take a lot of stress . A lot !!
