I think self-contamination is also a thing with herpes, like if you put your very own HERPES JUICE from a mouth eruption, directly on your eyelids (and iirc, herpes on eye is horrendous), glans... Strict hygiene is really the way to go, obviously
.!
Edit :
I'll add that the skin integrity plays an important role in defending from contamination/infections (that's one of the more important role of skin, generally speaking), and getting your face pummeled for 15 minutes can only increase the risks associated with herpes !
