I have also noticed that sometime after urinating , i dont feel empty/satisfied and also seems that some urine is still in my penis and after half an hour i have to go to urinate again (the
quantity of urine is not so much at that time) . I dont feel any pain at all during
urination, color of urine is quite normal and no other symptom of disease at all. I am a healthy man with 82 kg weight, Please advise me, whats the possible cause of my problem, is it prostrate problem ???
