Herpes type 1??

So my gyno called today and told me I have herpes type 1. Which is the cold sore virus. I tested negative for type 2 which is genital herpes. I've never even had a cold sore before nor have I done anything with someone who has! I'm kinda nervous about it. What's next? Does this make me gross? What can/can't I do now? Or is everything just gonna be the same? And I can only give it to someone else if I have a cold sore, right?
