Your oral symptom probably wasn't due to herpes. Cold sores do not occur inside the mouth. You more likely had a canker sore, which isn't caused by herpes. You might still have oral HSV-1 infection, since it is so common. But if sores in the mouth are all you have had, you need a blood test to know for sure whether or not you have HSV-1. Anyway, most likely your boyfriend is home free, at least for now.

if he already had HSV-1, he is safe. If not, there is a chance he will catch it genitally. I believe, in most cases, you have up to 21 days to see if anything happens.
Wow. I definitely did not know that cold sores do not occur inside the mouth. That actually is a huge relief. Thanks so much!
