I have an uncomfortable feeling in my urethra. I squeeze my penis in such a manner that I can feel the whole length of the tube I have discomfort. I have done std test and negative for all types. Just wondering what it can be. I m not passing stone but does feel like I have something in there. I have no abnormal pains anywhere else. I do not have discharge either. Almost feels as if there is small stones or even sand. It does not burn as I urinate or ejaculate, but do feel something in the urethra.
