[Question #12112] Oral Exposure Risk/ No symptoms

Hello. Nearly 4 weeks ago (Sept 18), I (M26) performed unprotected oral sex on a female CSW at an Asian Spa. Since the exposure, I’ve felt a myriad of mild symptoms I believe could be due to anxiety and stress. I’ve tested for pharyngeal gonorrhea and chlamydia, both coming back clean. I am now concerned about herpes and syphilis. 

The thing is, I’ve had no definitive clear-cut symptoms of either. I’ve vigilantly checked my mouth for sores since the exposure, and so far there is nothing. I know that herpes can be present without symptoms. 

My main concern is that I reconnected with my ex a few days ago (23 days post exposure) and we did some prolonged deep tongue kissing, and I worry that I could have passed on either of those to her.

 I took a full panel test yesterday, including HIV RNA, and should be receiving results soon, but as it was 25 days post exposure, I won’t be convinced of its conclusivity.

So for the question: am I overreacting in regard to the kissing? Would it be likely to pass herpes or syphilis through intense kissing in the absence of a sore? I may have more questions regarding testing windows and conclusivity, but for the sake of brevity, I’ll leave it for a follow up. Thank you.

Welcome back to one of our earliest customers several years ago, question no. 110. Thanks for your continuing confidence in our services.

Cunnilingus (oral-vaginal contact) is just about the lowest risk sexual practice of all -- probably not much more risk than kissing. I've never been aware of a single case of gonorrhea, chlamydia, or any other STD in either the vaginal or oral partner after cunnilingus. (Dr Hook was the senior investigator on a research study that found little risk for gonorrhea.) If you had asked before now, I would have said there was no need to test for any STD, but it's nice to hear your gonorrhea/chlamydia tests were negative. And the chance of herpes, without symptoms, is near zero as well.

Based on the combination of almost no risk plus your negative tests, there is no chance you infected your wife. And kissing is virtually zero risk anyway; she would not be infected even if you were. As for HIV, also zero risk or close to it:  to my knowledge, there has never been a reported scientifically documented case of HIV transmission by cunnilingus. Your HIV RNA test was unnecessary but will be negative. In addition, the likelihood your CSW partner had HIV or syphilis also was very low.

So in response to your main question, you indeed are overreacting. There is no realistic chance you have any of the infections you mention (or any other STD) or that your regular partner has been infected. If any tests in the "full panel" happen to be positive, it will not be from the Sept 18 event. I advise no more testing for either of you. Therefore -- and in reply to your closing comment -- I really wouldn't worry about window periods. Please do not have any more tests for anything.

I hope these comments are helpful. Let me know if anything isn't clear.

Thanks for the swift response and though I appreciate the welcome back, it’s strange as this is my first time using this service. 

For my peace of mind, I will still test for herpes and syphilis in 4 weeks time to be absolutely sure, but I appreciate the vote of confidence. 

Out of curiosity, what is considered a high-risk activity for a heterosexual male? I would think engaging in unprotected sex with someone who not only has multiple potentially unprotected partners, but also engages in transactional sex, would be a high risk. I’d appreciate some clarification.

Oops -- someone else chose the same username for the forum 9 years ago. Sorry for any confusion!

The herpes blood tests are not conclusive until 3 months after exposure.

As for "some clarification" my comments above were specially about the risks of cunnilingus, i.e. you performing unprotected oral sex on your partner. Vaginal and anal intercourse are much higher risk; fellatio (oral to penis) is low risk, but not as low as cunningus. As my comments above make clear, even if a female partner has an STD, it is rarely transmitted by oral sex. And contrary to what you seem to assume, at any point in time most sex workers have no transmissible STD. And when infection is present, for most STDs it it not always transmitted. For example, if a woman has untreated HIV, the risk for a single episode of unprotected vaginal sex is under one chance in 2,000. For herpes due to HSV2, it's about one chance in a thousand. Bacterial STDs like gonorrhea, chlamydia and syphilis are more frequently transmitted, but still not usually.

Let me know if anything else remains unclear.

It is now 6 weeks post exposure and still no clear cut symptoms like sores have shown up. Lately, however, I’ve been very itchy in my genital region. It isn’t always actively itching, sometimes it’ll just be little sensations next to the scrotum or in the perianal area. But it usually itches more when I’m moving around, like at work, and it’s noticeable enough that I can tell it isn’t an everyday itch I might get. The only thing I can link it back to is:

1) maybe 2ish weeks after exposure I had a slightly itchy scab patch on my scrotum, which healed and turned into a scaly rash on my scrotum. The “scaliness” promptly fell off within a day of moisturizing. Nothing like typical herpetic presentation, or any STD for that matter. I thought maybe it was fungal in nature, but would it return with a more pronounced itch weeks later without presenting the same scaly rash?

I also feel sudden short itching sensations on my face, but I don’t know if I’m just hyper vigilant for symptoms at the moment.

So more specifically my questions:

1) Since my exposure was oral, I worry that I auto inoculated myself and am experiencing genital itch as a result of ghsv. But would it be so persistent and with no sores?

2) As my genital itching currently doesn’t present with any rash, what would your guess be as to what it is?

Thank you

If I were teaching medical students to recognize symptoms that are unlikely to have a physical explanation and probably are the result of anxiety or other psychological origin, yours would be great examples. I am confident you are experiencing minor symptoms or even normal body sensations that you would otherwise ignore or not even notice. They do not fit with any known STD.

1) This does not happen. There is no such thing.

2) See above.

If your symptoms continue and/or you remain concerned about them, I suggest seeing a physician. I would imagine they would agree with my assessment, and perhaps advise professional counseling.

That completes the two follow-up comments and replies included with each question and so ends this thread. I hope the discussion has been helpful. Best wishes and stay safe.
