I talk about it in the context of safer sex, where I give people the information that I have (I sometimes test positive and sometimes don't; I don't have any information on what a test below the threshold but above zero means about transmission; I haven't had a cold sore in at least a decade) and let them figure it out. With other people, my policy is to use latex for oral during an outbreak or if they can feel one coming on; otherwise, I don't worry about it, including non-worrying on testing status for HSV.

The only reason I said it's a deal at all is that I hear genital outbreaks can really suck, and I understand the desire to avoid that kind of sucking.
