You can actually get herpes sores anywhere on your body provided that is the spot it went in. I know someone with genital and she has it on her vag and on her upper leg. The thing is herpes needs an entry point and the lips and the genital tissue makes an easier entry point so you commonly see them there. Your arm for example could get herpes there but it would take a bit more abrasion there to create the entry point as the skin there is tougher. The virus comes back at the point of entry as it moves through the nerves where it went in, then travels back to that location in an outbreak.
