HSV-1 on genitals.

Very confused.... told I have the type 1 strain on genitals and that apparently this is better than type 2 according to the nurse but it seems that the viruses are all mixed up after years of people having oral sex. So in theory I could have either caught type 1 from someone’s genitals or from their mouth? It doesn’t really matter regardless I guess. But if anyone has anymore information about the difference in the types it would be appreciated. 

No just hsv1 inside brain
