Thank you so much for the info. I have been out of the "game" for so long, it's hard to know what is going on sometimes...
No, gonorrhea would not last for 17 years or even 4 years. His issue is not going to be gonorrhea. NGU is a possibility which can be caused by common bacteria in the mouth that gets into the uretha that starts an infection, but without discharge I doubt that is an issue.
