Which are symptoms of gonorhea in males?

Painful urination. Please read this fact sheet from the cdc on stds: http://www.Cdc.Gov/std/gonorrhea/stdfact-gonorrhea.Htm. Also, see your doctor if you suspect you have an std.
Depends on site. Urethral: discharge from the penis, pain with urination, having to urinate urgently. Rectal: rectal pain or discharge (or no symptoms at all). Throat: sore throat (or no symptoms at all).
