First, the direct answer is no, there is no way you still have gonorrhea or chlamydia after the treatments you have had.
Second, your symptoms do not suggest any STD at all; no STD causes only the symptoms you describe. Urethritis symptoms are ONLY 1) abnormal discharge from the penis and 2) discomfort in the urethra itself, typically felt only as pain/tingling at the tip, without the 'bladder fullness' part. Viral STDs like herpes also do not cause such symptoms.
Your symptoms are absolutely classical for genitally focused anxiety, and that almost certainly is your only problem. You don't need any further STD evaluation or 'viral testing'. You have nothing you can transmit to your wife or that will ever harm your own health.

Thank you so much. This is almost a load off my mind. Still just a couple of paranoid follow-ups if ok - Is discharge always a symptom of Chl. or Gon.? Any chance that I could have resistant strain of something with limited symptoms? What about Trich? I'm leaning towards just guilt and obsession as cause now, but if had something earlier how long would it have taken for symptoms to go away after treatment?

Read innumerable threads in the HIV Prevention and Safe Sex forum for extensive discussions of HIV risks from heterosexual exposure.
