First, apologies to Dr. Hook for panicking during my last question. I’m a 57-y/o male who received unprotected oral sex for 10 minutes from a female on 3/15. Lots of deep kissing too. I began feeling a tingling in my bladder about 17/18 days later and slight difficulty urinating. I recently  noticed my right testicle is certainly bigger than the left, which led me to do some research and believe I have an irritated/swollen epididymis. However, the swelling seems to be the only symptom, no pain, NO pus/discharge and urinating is not painful. I’ve read one testicle is typically larger than the other, but haven't been examining until now. The swelling is less in the morning, more during the day. I am also coughing up some clear phlegm, no sore throat. So, my questions are: 1) Can the swollen testicle with no pain be the ONLY symptom of gonorrhea? 2) Is it possible that I contracted pharyngeal gonorrhea from deep kissing? 3) Might the swollen testicle be caused by an ordinary NGU?
