It looks like you changed your gender. If you need help with that, let me know.
So listen, assuming she has genital herpes type 2, given that she is on Valtrex and you are using condoms, the chances of you getting herpes from her are about 1-2% a year. (You have a better chance of getting someone pregnant using condoms or the birth control pill.)
If you just use condoms OR she takes Valtrex, it's about a 2-3% chance a year, should you all decide to not use condoms at some point.
Herpes (and other STDs) are not transmitted via hands. I'll include some links at the bottom that can help explain why.
If she has never had her herpes typed, she should. It may be herpes type 2, but could also be genital herpes type 1, which happens when someone with oral herpes type 1 performs oral sex on someone and it transmits to the genitals. It's important to know because the transmission rates are different, and the recurrence and shedding rates are really different, and it may affect her treatment choices.
So. If she has hsv2, are you going to be anxious every time you have sex? Is this just something you are getting used to? (Either of these are fair, and you are entirely within your rights to have whatever feelings you have on the matter.) If you don't think you'll ever be able to be at peace with it, and maybe that's not something you know yet (also fair), then let her find someone who will be. She is not a walking, talking biohazard. Obviously, no one WANTS herpes. You just have to be comfortable with the risk.
