Welcome to the forum.
Replying to the question as posed in the title: Saliva rarely transmits STDs, if ever; and liking intact skin -- whether of the scrotum or anywhere else -- is not a risk for any STD.
Now I have read the question itself. Your own evaluation is correct: "From everything you've said in the past on other posts, I believe that I have next to no risk for an STI". (Except I would delte "next to". There was no risk, period.)
As for your urethral pain, all the evidence is against an STD. In the absence of an abnormla discharge, the symptom itself isn't highly suggestive; and you've had negative STD tests as well as testing for urethral white blood cells as would be expected with NGU.
The reason bactroban isn't helping is that no infection is the cause. Perhaps it was worth a try, but my guess is your doctor didn't really think it would help.
Sorry I can't say the cause of this symptom. However, I'm sure you have no STD, and no other infection related to the sexual exposure you are concerned about. You'll just have to keep working with your doctor on it.

You were not at risk for NGU. There is no way you can get NGU (an infection in your urethra) from exposure of the skin of your scrotum.
Many doctors don't entirely understand the difference between NGU and UTI. But by saying you had no evidence of UTI, I'm sure your doc meant no white blood cells, which means no infection of any kind, either UTI or NGU.
Bactroban has no effect on NGU. That's not why you were prescribed it.
That will end this thread. Do your best to move on with no worry about STDs.
(Glad I got this last question in before you replied) If I had NGU would the Bactroban cure it or would i need a course of oral antibiotics?
Can the same be said for sucking into the mouth since that would involve contact with the mouth itself?
The Dr. looked at my urine and said that I don't have a urinary tract infection. Is that the same thing as "testing for urethral white blood cells"? I guess my main concern is the NGU at this point. What I'm saying is, would NGU present as a urinary tract infection?
Sorry to post about this again. Went to GP about my urethral pain. He said that I could possibly get internal herpes from oral sex and therefore not have any external symptoms. So my final question (I swear!): in the extremely unlikely chance I could have gotten herpes from having my testicles licked, could the herpes manifest in or on my penis, or really only on my scrotum since that was the point of contact? Thanks and I really appreciate your help.
Herpes indeed can result in internal urethral lesions. However, your urethra wasn't even exposed; and most people with urethral herpes have much worse pain than you seem to have had, and also would have abnormal urethral discharge. Plus very sharp tenderness of the penis at the site of the urethral lesion.
In other words, forget herpes. No way.
That's definitely all for this thread. No more comments please -- and also no new thread on this forum with the same or follow-up questions. Do your best to move on without worry.
