Thanks for the answers! As far as I know, I do not have any herpes (never had an outbreak), and the new sexual partner I am going to have sex with also is unaware of having any herpes, and was tested for stds 5 months ago. My only fear is that either one of us has HSV 1 and is unaware, and can transmit the virus when we perform oral. I'm guessing that as long as there is no cold sores visible, it is a low risk.
