Girlfriend Kisses Me When I Have a Cold Sore?

I've had cold sores since grade 7, please don't share drinks haha

Anyway whenever I get a cold sore, she insists on kissing me.

I told her they are contagious but she says she doesn't care, all I can do at that point is turn away, in which she gets offended.

Should I just not see her when I have cold sores? What would you do?
