No, some people have herpes their whole life and never show symptoms! You could be infected by someone and 20 years down the line finally find out, or you could never find out... or you could sleep with someone infected and next week have an outbreak. It all depends on you. Sorry to hear what happened, you're not alone! Your boyfriend should get tested as well.   If he's not in an outbreak (no sores) then they'll do a blood test, it CAN say negative and he IS in fact infected. The only REAL way to tell is if he gets an outbreak and he gets a viral culture done. With blood tests, their only looking for "signs"... with a culture, they scrape the sores and look under a microscope.   Take care!
