Welcome to HCM. I read your question carefully and I understand your concern.
HSV-2 is usually transmitted by vaginal and/or anal sex. But, you can also get infected with HSV-2 from one person's genitals to your mouth, resulting in oral herpes. By kissing usually is transmitted
HSV-1. It can also spread from mouth to genitals during
oral sex (fellatio, cunnilingus and/pr analingus). This leads to
genital herpes.
In persons with asymptomatic
HSV2 infection, genital HSV shedding occurs in 10% of days and on most of those days the person has no signs or symptoms. So, the virus may spread also during times when there are no symptoms and from sites that are seemingly inactive.
In some studies of transmission of genital herpes, the anual risk of transmission averaged 7-10%/year for those abstaining from sex during outbrakes.
In conclusion, the best way to avoid transmission is to abstain from sexual activity during outbreaks and to use condoms the rest of the times (even though condoms afford some protections, since they might not cover the site of an active virus).
I hope this information was useful. I wish you a good health
