It seems to me you are overreacting a bit. In general herpes isn't such a horrible deal that should so radically alter the sex life of people in mutually caring relationships (which is how I interpret your term "important"). If you want absolute, total protection against herpes, your best bet is to forego sex with this person and find an uninfected partner.
The main strategies to prevent genital herpes are 1) avoid sex when the infected person has symptoms; 2) use condoms consistently (which are highly protective, although not perfect); and 3) antiviral therapy of the infected person. Consistent use of any 2 of these methods is highly protective; and consistent use of all three may come close to 100% effectiveness.
Herpes does not often infect the scrotum; for practical purposes, only your penis is at risk. HSV-2 is rarely transmitted to the mouth; and when it is, typically doesn't cause symptoms or recurrent outbreaks. It can happen, but not frequently enough to take special precautions in cunnilingus except to avoid it if/when your partner is having an outbreak. In any case, I find it difficult to imagine a bigger turn-off (for your partner, if not you) than having sex wearing jockey shorts; and most people feel pretty much the same about dental dams (which no longer are seriously recommended by any health authorities).
In today's vernacular, does a "date" always mean sex? Perhaps you will agree that dinner and a movie would be safe.... ;-)
Bottom line: Herpes isn't a big enough deal to be as concerned as you seem to be.

I have HSV2 and have been having unprotected sex with my girlfriend for over 8 years and she has not caught it from me yet? So I think if you follow the basics. Valtrex daily for her and don't have sex when she is having an OB you should be pretty safe and if you throw in a Condom then I don't think you need to worry one bit.
I caught mine when I was young and stupid, the girl I was with had an active sore that we both talked about but she said it was where her underwear rubbed her raw when she was working out at the gym. STUPID ME! Prior to that we had sex for a year without any problems, she said she did not know she had it?
