Well, yes, you can still get herpes (HSV1 or HSV2) from her even though she is asymptomatic (without symptoms). In fact, around 80% of people are asymptomatic (without symptoms). So, it is possible for you to have herpes and not know it. Additionally, it doesn't matter what you do intimately with her, there is always a risk of catching herpes. Herpes can be picked up so easily, you can get it from drinking from a glass of water she just drank from ... think about that the next time you drink after your buddies.
