Hi, if you have been kissing her while she had a cold sore, there is a very big chance that you now also have oral herpes (whether you show symptoms or not). Herpes can also be transmitted while there are NO symptoms present. If you have contracted oral herpes from her, you are at risk for giving it back to her genitally, even if you don't have symptoms. However, by her already having herpes orally (which is it estimated that 80% of the population already has), it does give her some protection from getting reinfected genitally, since her body already has antibodies to it. It is, however, still possible. Hope that helps.
