That makes sense, for sure – she could have given this to you from a cold sore – I thought you were implying that you got it from intercourse with her, stating that she has genital HSV 1.
I would not advise abstaining from intercourse if you are both positive, no. It is very unlikely that you would spread it to a new location on your body. In all of my years of practice specializing in herpes, I have only had ONE patient who said she had a history of cold sore and got genital HSV 1.
