I have dealt with cold sores all my life, so they are nothing new to me. But I haven't had one in probably a couple years. Recently I've started seeing this new guy and we kiss and make out of course. A couple days after that a cold sore popped up. Right when that one healed, I got another one in the same spot. He said he has never had one before. Is this somehow causing my cold sores to flare up again?
