decreasing the chance of spreading HSV virus as much as possible

Dear Doctors,
I am HSV 2 positive since 2 years ago. I have outbreaks 2 times per year which are not annoying. I don't take any medication, and everything seems to be fine with respect to my health situation. My only concern is spreading virus for instance to a new girlfriend.  I know that suppressive therapy and condoms can help in reducing the chance of spreading virus. Here are my question concerning this issue:
1- Is there any way, even very expensive to reduce the risk of spreading the virus much below than what suppressive therapy can do? For example, taking higher dosage of Valtrex? At this point, I have much less concerns about possible side effects.
2- Does washing the genital area with a proper material before a sexual activity helps in reducing the risk of spreading the virus?
3- Is there any quick test which can be done on my own in order to check presence of the virus on the skin (Viral Shedding)? This help detecting those Viral Shedding with no visible sore and thus further reducing the chance of spreading the virus.
Thanks for your help in advance
