General answers and advice is less restrictive than what is technically possible. I'll give a personal example. I have HSV2, but orally not on my genitals. Was trying to figure out the risk of spreading it oral to oral. General advice is not unless outbreak, but technically possible since research shows can have virus present without outbreak. Notably with oral HSV2 another outbreak is almost guaranteed not to happen (and I've never had one since and it's been about 10yrs).

In any event, I wasn't satisfied with the potential discrepancy and actually emailed researchers listed on papers and was pleasantly surprised by most responding. My take away was that while none wanted to give me advice beyond referring to official sources (which for HSV2 is generally limited to genital contact), because can't rule out oral to oral happening. But they did note that if I ever thought I spread it via oral-to-oral to reach out to them because it would be a case they'd like to look into...

So outlier risk they can't rule out, but one that people shouldn't factor into their ordinary lives. So I have disclosed to all sexual partners (in certain cases preempting their status as a sexual partner, lol), but not a risk I consider otherwise with caveat of anyone I think may be immunocompromised.
