Look, I don't care about the karma, but does this downvote mean that HPV-1 is equally transmissible during an outbreak as in latent phases? Because if so, those 2/3rds of the world's population would all need to cut out oral sex from their lives.
In response to another question in this thread, the safest way to "diagnose" herpes in others, is probably to ask them. If they don't know (haven't been tested lately), assume they're infected. And if you can't trust them to tell the truth, you probably have no business being (physically) intimate with them... (Not meant as a moral judgement, just as an observation).
Second, you're being downvoted because oral outbreaks can be very mild and may just look like acne, or a razor burn, or any number of other normal dermatological conditions. "Just looking for it" is perhaps the worst way to possibly think about any STD.
