Transmission probability from oral-genital contact

I am a 60 year old male, HIV+ for 23 years, asymptomatic and on maintenance therapy.

I had very brief oral contact with the penis of a man whom I have known informally, but with no information about his health status.   Although I could detect no symptoms of HSV-2, nor was there any fluid (pre-cum) noticeable to me, is it possible to measure a risk transmission probability for this kind of activity?  How frequently would a HSV-2 infected male actually shed virus during asymptomatic periods?  Would shedding occur from the mouth as well as genitalia?  In this scenario, should I have blood work done?  Appreciate your counsel, with good wishes.

it's not ejaculate that transmits the virus, it's the direct skin on skin contact of the sex act itself that is the risk.

it's low risk of contracting hsv2 orally.  really no stats to provide since it happens so infrequently, we can't really come up with them.

have they ever tested you for herpes since you are hiv+?

Dear Grace; thanks for your reply.  I have been HIV+ since 1988; I was tested across the STD spectrum a number of years ago and nothing remarkable was found.  I have very little sexual activity these days; hence my concern over this one awkward adventure.  I will ask my physician on my next scheduled visit to draw enough for a big range test, including HSV-2.  I do very much appreciate knowing that there is little data on oral transmission; being at the lower end of the risk scale is good to know.  best regards.

just make sure herpes was part of your std testing since it's typically not a part of routine std testing.  I assume your hiv is well controlled but hsv2 can complicate it so knowing your status is important.
