If you are having sex with someone who is documented HSV 1 and 2 negative, you may want to consider daily antiviral therapy to reduce the risk of transmission. But go with test results on that one, not just an opinion as most people infected with HSV 1 and 2 are not aware of their infection. i don’t know about dental dams – you should discuss that with a potential partner. It or something like it would be the most safe, yes.
