If it's HSV-2, oral sex is safe. HSV-2 does not settle in the upper spine and therefore no shedding (contagious) can occur. HSV-1 (oral herpes) can live in the upper spine and lower spine-- that's why people can get infected in the genitals from oral sex. Check out this website: http://consults.blogs.nytimes.com/2010/06/18/giving-your-partner-herpes/. I believe it discusses this subject and I find it a very useful column.
