There is a risk for the giver of unprotected oral sex to a female infected with HSV2. There is also a risk for a male having protected vaginal sex with that same HSV2-infected female. I'm curious whether one carries more risk than the other.
Said a different way, if I accept the risk of acquiring HSV2 from a female through protected vaginal sex, am I at more, less, or similar risk of acquiring HSV2 by giving her unprotected oral sex?
I know from studies cited here that the risk of a female transmitting HSV2 to a male is something like 1-4% over a year, assuming no sex during outbreaks and sex twice per week, or so. So, I'm looking to compare the risk of transmission from the female to the male, orally.
Oral hsv2 is uncommon, and herpes doesn't go from the genitals to the mouth as easily as it does from the mouth to the genitals.
So long as the infected partner doesn't have an actual partner, I wouldn't worry about oral sex.
If oral hsv2 does happen, it rarely recurs, rarely sheds, and rarely transmits.
