Sex last night with someone with herpes

After having sex, my partner told me she has herpes (note - not a great way to start a relationship).  She said she is symptom free and taking medications (nope, don't know what type).  We had unprotected oral sex (giving and recieving) as well as protected vaginal sex.

Is there anything I can do to lesson the chance of infection?  Can/should antiviral drugs be taken after exposure?

I don't think there's anything you can do to necessarily lessen your chances of infection since the deed is done.  But, you have about 1% chance of being infected, or 99% of not being infected since she takes suppressive medication, isn't experiencing an ob, and you guys used a condom.  At least this is what I gather from my research.
