After I ejaculate, I get a burning/stinging pain inside my penis near the tip. This makes me need to go to the toilet for a pee(even if I cant), which helps a little. I usually sit on the toilet for about half an hour to get rid of the pain. I m then left with a mild discomort for another half-hour or so.I ve looked on the web and found others with this problem; they have been tested for std s, Uriny tract infections, and nothing comes up as the culprit.Sometimes I don t have this problem for months, and other times it can happen just about every time I ejacutlate.
