I am a 36 year old male, father of 7 year old boy, staying in gurgaon I am having an issue since past few weeks wherein after having intercourse, a white/ slightly yellowish substance (flakes/ small lumpy) comes out of my penis (sometimes along with sperm or after few hrs later). It is not painful but a symptom which is bothering me back of my mind please suggest if I need to worry about this or not. I read somewhere that it could be a sign of ageing.
