[Question #7299] Genital Herpes to Mouth Infection Odds

4 months ago
Hello,

I’m a 23 year old male and I’ve had herpes for 1 year now and have been taking a daily dose of 500 mg of Valacyclovir  and used a condom every time I’ve had sex.
 
A woman I’m seeing is aware of my condition and wants to avoid oral sex (blowjobs and such) until she finds out the risks involved.

In terms of percentages, if she were to blow me without a condom on, or if I were to eat her out without protection, what is the figure we’re looking at here? 1%, 5%, 10%, 20% 

I’m also curios the chance in terms of percentages of me giving her herpes having vaginal sex with a condom on and on daily medication. AKA, taking all  precautions.

Thank you

We don't have any data at all on the transmission of HSV 2 (is that what you have?) via oral sex.  If you are infected only orally, the risk of giving herpes to her by giving her oral sex. 
The risk of transmission to her if you are using a condom with every intercourse AND using daily antiviral medicine, having sex on average twice a week is about 1-2% per year.

Understood. I have HSV 2 and am infected on my penis. At this point, there is no data on transmission from my penis to her mouth? Or are there any risks associated with this at the moment?

Correct, there is no data about that.  There is probably some risk, yes, but I think is low as HSV 2 doesn't like the oral area and also because you are wisely on suppressive medication.

Lastly, I wanted to confirm with my doctor that it was HSV-2 on my genital and got this response...

“Herpes is interchangeable so you can have herpes 1 and 2 on genitals and usually 1 on mouth but can also be 2” 

Is this true? If so, I think I’m confused because then I would not be able to confirm that HSV 2 is on my penis and that transmission is low to the mouth when reviving oral sex.

Thank you for all you help

Your doctor is partially correct but they seem to not understand the very clear need (and CDC guidance) to always type the virus as genital HSV 1 has a very different course than HSV 2..  But that doesn't really answer the question.  Did you swab test come out HSV 1 or HSV 2 positive?  You need an actual copy of the test to know.  I am going to leave this thread open until you find out if your swab test was typed and if so, which typed you have.  If your swab test was not typed, that was an error and you'll need a type-specific antibody blood test to know what you have.
