HSV-1 and HSV-2 Infections

[chrome-lover.livejournal.com]

Hey, I have a question for you all. My boyfriend has HSV-1 (oral herpes) and I guess I have it too (my last cold sore was five years ago). My question is, how easy is it for him to transmit HSV-1 to me as genital herpes (HSV-2)? I know it's possible, but I'm wondering, if so many people have HSV-1 (~80%) then how come more people haven't accidentally transmitted genital herpes (20-25%)?

Thanks!
