I would think it highly unlikely that you would transmit the virus
back to your girlfriend genitally.  After all, she has probably had
oral HSV-1 for some time and, therefore, cannot be reinfected by the
same type elsewhere.  If someone hasn't suggested it already, read the
Herpes Handbook at www.westoverheights.com.  I found this handbook
very helpful.  I passed HSV-1 to my husband during oral sex because I
was clueless that it could happen.....wish I had been given more
information long ago.  If you're like a lot of people (my husband
included) your HSV-1 genitally won't present symptoms often, if ever.
My husband hasn't had another outbreak since the initial one a year
ago.

That's not likely since you already have herpes and so does she.

You can't pass it back and forth like that.. know what I mean?

Hope this helps,
