I recently was with a guy that I think may have herpes. I've never asked him if he does, but he basically slept with a friend of a friend of a friend, and I know that one of those people has it. We've never had sex, but he has touched my genitals. I have never touched his (only on top of his boxers). What is my risk of getting it, if he did have herpes? This is the third time we have had contact over the past 2 years.
