Welcome to the forum. Your question came in while I happened to be on the forum. Most users shouldn't expect immediate replies! And thanks for obviously reading other threads with issues like yours (as indicated especially by question 5).
Your symptoms are really not suggestive of any STD, and certainly not genital herpes. As has apparently been the case for you, when we see patients with such problems in the STD clinic, we usually find nothing wrong at all. Your last question suggests you won't be surprised when I say that the most common explanation seems to be he that anxiety or other stresses have led to a heightened awareness of normal body sensations, or of minor symptoms that don't indicate anything wrong.
As for herpes, both the minor nature of your symptoms and their pattern are wrong. HSV doesn't cause the relatively frequent (nearly continuous?) symptoms that it seems you have. And herpetic urethritis typically is severe, with major pain on urination -- not just a minor tingle or itch. (Over the years, I've had a couple of patients who described herpetic urethritis as the worst pain they ever experienced.) And herpetic urethritis would produce WBCs.
To the specific questions:
1,2) This symptom does not suggest urethritis of any kind and normal WBCs reliably exclude urethritis of any cause, whether bacterial or viral.
3) Since you have no apparent urethritis, M. genitalium is an unlikely cause of your symptoms.
4) As discussed above, I'm confident this isn't herpes. If you want even more security about HSV-2, you could have a blood test. As you point out, merely on a statistical basis there's probably a 25% chance of a positive result, something you might want to know regardless of your symptoms. But if positive, it wouldn't explain anything; in that event, I would conclude that you have asymptomatic HSV-2 plus unexplained penile tingling.
5) I don't think I would classify this as CPPS, which usually has a component of pelvic or testicular pain (as the name itself implies) and often urinary urgency or frequency, which you don't mention. But as my comments above suggest, it's possible this is indeed part of the spectrum of genitally focused anxiety, which is often part and parcel of CPPS.
The bottom line is that I really don't think you should be worried about this, and I see no clear need for any further medical evaluation. But if you remain unconvinced or if the symptoms worsen, consider seeing a urologist. If you do, I recommend you print out this thread -- it might be a good framework for discussion with the doc.

With this additional information, a prostate problem -- whether CPPS or true prostatitis -- seems quite plausible. A urologist will be able to work it out. In the meantime, don't lose a lot of sleep over this. These conditions are generally inconveniences, not serious health threats. The reason for a urology evaluation is to make sure you aren't the rare person (especially at your age) with a more serious prostate problem -- but most likely you have nothing that will ever seriously harm you or a sex partner. And almost certainly no STD.
Thanks so much for your detailed response to my questions! It's gone a long way towards providing me with reassurance (on the herpes issue in particular). I know you can't engage in endless back and forth (I promise this will be my final comment!), but I just want to respond to your follow-up questions:
- You ask if my symptoms are "relatively frequent (nearly continuous?)", I would say they maybe occur every 2-3 months, but I don't always notice precisely when they begin and end (wish I'd kept some kind of a diary).
- "pelvic or testicular pain" - perhaps at times there is a feeling of testicular heaviness. Right now, I feel aches between testes and leg (inguinal lymph nodes?) and on my leg.
Last year, around the time I was first concerned about ejaculation force, for a time urine flow was somewhat abnormal. No frequent urges, but there was definitely a kind of post-void dribbling (thankfully now gone). Would these 2 issues (reduced ejaculation force and previous voiding concern) suggest I might benefit from a closer look at my prostate?
