I’m a healthcare worker and have seen my fair share of herpetic ass lesions, anal warts and far too many cases of Hep B (completely avoidable with a series of low cost vaccinations)..... all of which can be transmitted to or through your ass via an infected tongue mouth and lips. Seen it, it ain’t pretty. I’m in the game too, so I play the odds as best I can and realize there are no guarantees. I’m just stressing don’t trust internet scientists presenting their hopes, thoughts and desires as facts. Everyone should Get a Hep B vaccine, if you’re young get HPV vaccine and if you see any hint of sores, chapped lips use your head and cover up. That way at least the odds are more on your side.
