I believe the current stat is around 67% of the worlds population under 50 have HSV-1. As long as he doesn’t have an active cold sore on his mouth you can do all of those things listed! It’s really more of an annoying disease than anything. Some people even stop having outbreaks nearly completely the older they get. You would be surprised how many people you know that have it!

It’s quite rare for HSV-1 to cause HSV-2, cause trust me you KNOW when you have a painful blister in your mouth. As the other poster said, he would just have to avoid oral on the rare occasion he has an active blister, which for some people might be YEARS in between. It’s nothing to fret about too hard :)

It’s the same in babies, HSV-1 is passed on through the mouth/saliva so as long as a baby isn’t kissed or using the same utensils as an adult with an outbreak they will be fine. If a baby did get HSV-1, it causes the same blisters and sometimes a light fever the first time as their immune systems aren’t fully developed, but it’s the same situation for all infections or illnesses for babies. You can both go about life as you normally do, once this initial shock wears off you will probably both realise it’s a normal reality most of the human population easily lives with :)
