I have a new partner who states that she has HSV-2. She contracted it "years ago" and has only had two subsequent outbreaks (again, years ago). I myself experienced the onset of buccal / lower lip HSV about 20 years ago directly from (5 days after performing Cunnilingus) that recurs once every 12-18 months. There is a significant prodrome when an outbreak is pending (enough that I can start Valtrex prior to formation of a lesion).
What are the odds of me developing genital HSV from unprotected sex if she's asymptomatic given our history?
Can I take Valtrex as prophylaxis?
