I wasn't sufficiently careful in that comment. I should have said low transmission risk, not zero. But anyway this is completely irrelevant to the sexual exposure, since you are immune and simply cannot catch a new HSV-1 infection. Please try to understand that and get beyond your concerns about it.
Hi Dr. Handsfield,
Thanks for your prompt reply. I had a question about your quote "Oral to skin contact carries no STD risk -- whether the skin of the scrotum or anywhere else. Intact skin is not susceptible to STDs." Don't some men get genital HSV-1 on their penis from receiving oral sex from a female that has oral HSV-1? Does that mean that the skin of the penis shaft is tearing or cutting from the oral contact? My impression of herpes was that it had to be massaged into the skin which could happen even if the skin is intact. Is my assumption wrong? Could you clarify on this? Thanks.
Welcome back to the STD forum.
Oral to skin contact carries no STD risk -- whether the skin of the scrotum or anywhere else. Intact skin is not susceptible to STDs. Testicular discomfort like you describe is not suggestive of any STD. And in any case, STDs that involve the testicles get there by traveling up the urethra, and your penile exposure was condom protected, so STD from this exposure isn't a possible explanation for that symptom.
1) You read correctly. Your history of oral herpes and your positive test for HSV-1 mean you are immune, or at least very highly resistant, to a new HSV-1 infection anywhere on your body.
2) What you should "make of that" is in the opening part of this question: "anecdotally". For the reason just discussed, such stories are rarely reliable, if ever.
3) As already discussed, not herpes. And syphilis does not cause symptoms like this -- not a chance. The first symptom of syphilis is always a sore, which cannot start sooner than ~2 weeks (usually 3-6 weeks) after exposure.
4) Irrelevant -- not possible. But primary herpes (or a primary outbreak), by definition, is a person's first infection with HSV, anywhere on the body.
5) There is a very small risk of transmission of oral HSV-1 by oral sex, even without an overt cold sore. But it's very tiny and not worth worrying about.
6) HSV IgM testing is never useful and certainly would be a waste of money in your case.
The most common explanation of the sort of testicular discomfort you describe, especially when it also radiates into the lower abdomen, is the chronic pelvic pain syndrome (CPPS). It used to be considered a form of prostatitis, but the prostate might not be involved at all. CPPS is often (usually? always?) a manifestation of genitally focused anxiety. For more information, google the term (spell it out) and start your reading with the excellent Wikipedia article and the information you can find from the Stanford University dept of urology. Last time I looked, both were near the top of the google hit list.
But you can forget herpes, syphilis, and any STD from the event you describe.
