Dating and Cold Sores?

After my last relationship I noticed that I started getting cold sores around my mouth. After some reading I found that it's caused by the virus and cannot be cured although the majority of the population has it. My dilemma is I've met someone I like and have been on a few dates but haven't kissed her and I think she might be thinking I'm not interested. I'm hesitant because I feel like I should disclose this to her before kissing but both my doctor and my med student friend said not to worry about it - I don't tell them I have the cold virus (which is incurable as well). Its just that everyone talks about the STD and how bad it is but never about the cold sore - it's like everyone treats it as two completely different viruses. I want some advice - should I disclose (and kill the romance over something that most people have) or not disclose (and have her resent me for not being up front and giving her something to remember me by)?
