sterile means normal and no sign of infection.
about 8 months ago. something hard had struck the skin of penis by corpus cavernosa the penis went purple for few days and I couldn't have erection for few weeks. since then I have started to get good erection but not long after trauma. urine started leaking after finishing urination. when I don't need to urinate I don't feel a need to pass urine and I urinate 4 times a day
yes I have but I'm asking you from your years of experience what the problem can be
