Female genital HSV2 exposure to male

May I ask for a medical provider's input as to the following:

1.  Oral exposure.  36 days ago, I performed oral to genital sex on on a woman with HSV2.  She was not having an outbreak at the time.  She was diagnosed 5.5 years ago.  Question:  I'm concerned about the risk for exposure.  Dr. Leone says it's 99% impossible to transfer genital HSV2 to the mouth.  But Dr. Handsfield does not seem to echo that same position in his posts.  Should I assume this is a part of the 4% transmission to male, over a year period when no outbreaks?  I have not seen any oral symptoms except chapped lips, which goes away with moisturizer.  If there was transmission, how likely would it be to be asymptomatic 36 days out?  If I had symptoms, would I know it?

2.  Vaginal intercourse, without a condom 21 days ago, while the woman was on her period (3 x over a 12 hour period).  The woman was on Valtrex at the time for 9 days prior.  She noticed a "small bump" 9 days prior, took Valtrex and it was gone by 6 days prior.  I have not seen any genital symptoms.  11 days ago I had a blood test that was negative for both HSV 1 & 2.  Question:  I'm concerned about the risk for exposure, especially since she was on her period.  Should I assume this is a part of the 4% transmission to male, over a year period when no outbreaks?, then reduce it to 2% since on Valtrex, then increase it to 3% since she was having her period?  So is it fair to say that if I were to do this 2x/week for a year, my risk would be 3%?

3.  Have you ever heard of a case where someone got HSV-2 from the above facts?

  Thank you.

Oral HSV2 is very rare, it just doesn't take hold too readily. The chance would be well less than 4% over a year of sex, but not many stats on this. Perhaps the fact that about 3% of HSV2 infections are oral gives an indicator of the much lower transmission chance.

I'm not convinced menstruation increases the chance of herpes transmission for all women, some sure.

Valtrex must be taken every day to get the reduction of 50% in transmission and not just preceding an outbreak.

Your maths as an average is close enough. Individuals can vary from 0% to perhaps 12% depending on numerous characteristics.
