Yes, that I knew, but there are a few bits I'm not sure of. I'll restate my question and add a new one for clarity.
Say there are three people, one has herpes, two don't. If one person who -doesn't- have it kisses someone who -does-, and then the person who -doesn't- have it gives oral to the other person who -doesn't- have it; will the person receiving oral get genital herpes?
Another question. Can the person who does have herpes give oral to people who don't?
I do know though that herpes of the mouth is very very common, and is a different yet similar virus to genital herpes.
