I am experiencing a slight tingling in my urethra. I am a 31 year-old male. No pain, discharge, foul-smelling urine, swelling, fever, nausea or any other symptoms. The frequency of my urination has increased, but that may likely be due to the increased volumes of water that I am drinking. I have had kidney stones in the past and thought that the sensation may have been the precursor to another, but none have passed.
