It is a good question and it definitely can happen that way.
The skin does have defenses and virus has to land in the right spot to find a nerve ending and be rubbed toward it.
Another theory could be that as we get exposed to HSV1 on our mouths a lot in our youth that the defenses get refined in the oral area that makes it harder to be infected as an adult. Not sure how true this is but I do know that adults seem to have a low infection rate of oral HSV1 despite many having partners with it.
No my partner did not have hsv1. However he was aware that as a child I contracted it. My question is why would it spred to his genital are before his mouth considering the mouth had the most contact and the initial contact?
hi, if a person already has hsv1 oral the risk for getting it in the genital area is close to zero if possible at all as you have antibodies to help prevent this.
I say this to answer your question. It can be passed to both the oral and genital areas and those that have it in both areas got it at the same time when there were no antibodies build yet.
