In fact, by following proper lifestyle with healthy food, proper workout, calm mind & apt supplements it can be well taken care of. Do read "Living with Herpes" article.. It is extremely important to understand that we need to boost your immune system to be able to fight. You may try combinations of various herbs & ingredients like Hypericum mysorense, homeopathic bio-energetic imprints of herpes, prunella vulgaris, monolaurin and Picrorhiza kurroa which are the best to boost your immune system with this regards.

First, try to remember that you don't know that what she had on her mouth is herpes. It could an allergic reaction, something called Behçet's disease, cheilitis, or any number of other things.
If it is herpes, and she had outbreaks, there is a chance you'd get it. It's impossible to put a number on this - no one knows where she was in the outbreak process, how much virus was present, etc etc.
I wouldn't be freaking out now, so you can stop. If you don't already have hsv1, you'd likely get symptoms within 2-20 days. You can ask your doctor for a type specific IgG herpes blood test. If it's negative now, and positive later, you know it's a new infection.
Please do your skin a favor and stop shaving, at least for awhile. All signs are telling you to stop - you are "enraging" it. If you must groom the area, get some trimmers or something, and trim the area, but shaving is only causing you harm right now. Most women don't mind it unshaven, so long as it's neatly groomed. Trim it down to almost nothing if you want, but give your skin a rest. :)
