As for whether this is HSV or not, if she gave it to you, why do you have a new rash
too. Conversely, if you gave it to her, why do you have a new rash
. Furthermore, location and extent of lesions is atypical for HSV. This could be related to scabies or some other infestations or a reaction to some sort of cream of lotion that you both got on it.
The best thing you can do is not squeeze it (as I said before).
