I've never had a cold sore. Last I checked I'm negative for HSV-1 and HSV-2 antibodies so I haven't had enough exposure to either herpes virus to have a detectable response to them. But most of the world does to at least one. I probably wouldn't go around French kissing ppl with cold sores but also it would be understandable if they did have cold sores. It's hard not to have herpes based on how prevalent the viruses are tbh
