HSV 2 transmission Oral To Genital and Vice Versa

[Cooper2347]

I have HSV-2 and I came across a post I had similar questions about. If my partner performs oral on me and she contracts oral HSV-2 does that serve as a preventive measure or sort of vaccine of passing it to her genitally since she theoritally has it orally? I read once you have HSV in one place it's highly unlikely to contact it again in a different area?  So for instance since she performs oral on me and I transmit HSV-2 to her orally would that prevent her from getting it genitally? We use comdoms every time we have sex and she's been wanting to perform oral on me, but without the use of a barrier and I am looking at the risks if she were to give me oral and what the outcomes would be. Any advice would be helpful

You are largely correct on the assumption of an oral infection most likely preventing a genital one. There are no guarantees but this is pretty accurate.
Hsv is rarely an oral infection. It doesn't like the oral cavity and we're not exactly sure why.
All in all her risk factor for getting oral hsv is very low. On a side note condoms have been shown to protect the female against hsv better than the male
