Have you ever had a cold sore, chicken pox, shingles? All the same virus. Never had anal sex either. Doesn’t stop the virus from showing up there. If you wipe yourself you are probably distributing it. You can get herpes simplex 1 where you normally get 2 and visa versa. Doubtful if vaccine caused . But I am not a doctor, just someone who has lived with it. Comes and goes. Can be dormant for many years then something happens, illness friction, in my case radiation and it flare up again. Bidet is your friend at times like these.
