Whether HSV-1 or HSV-2, almost certainly herpes is not the cause of the rash/irritation in your groin,
for several reasons. Recurrent
genital herpes due HSV-1 is rare. Many people have no recurrent outbreaks at all, and most of the rest have only 1-2 outbreaks over a couple of years, then none. When there are recurrent oubreaks, it's usually on the penis.
