Since you asked for comments, I think you need to relax.
Since she takes valtrex, if you were with her in a long term, monogamous relationship, as long as you avoided sex during an outbreak, there'd be about a 2% chance you would get it over the course of a year. That's a 98% chance you wouldn't get it. You have about the same chance (or worse) of getting a female partner pregnant when she's on the pill. You can do the math for breaking it down into a one time encounter if you want - clearly its a very low chance.
You didn't even have sex. Oral hsv2 is RARE, and with that and the valtrex, I wouldn't worry about it at all.
Aj
You don't have anything to worry about here.
I checked, and it doesn't seem you've made it to the doctor's forum yet. This is the forum you want -
