HSV-2 is typically genital herpes. The virus is spread by coming in direct oral, genital, or anal contact with the virus. HSV-2 could also spread to a partner orally. Avoiding sexual intercourse when any symptoms are active will greatly decrease the chance of passing herpes to a partner.
If you have genital herpes, and if your partner doesn't had oral herpes the virus could spread if she performs oral sex on you. If she's negative for oral herpes, she may come in direct oral contact by performing oral sex on you. The chance she will catch oral HSV-2 isn't high. I would recommend having safe sex with a latex condom. Dental dam could be used for safer oral sex. The chance of passing herpes to a partner could be very low if safe sex happens. The virus could go undetected. We can never be 100% certain that herpes isn't on the surface of the skin. We also know that herpes only spreads when the virus is on the surface of the skin.
Dating someone with HSV 2 is not one people's thing, it is related to the fate of two people. So safe sex with condom is necessary。
