Can someone please answer my inquiry?
This sounds very strange. I think the circumstances need to be investigated further. I am not sure how it is even possible for HSV2 to infect nipples!
I think your friend should return for further testing and understanding of the tests undertaken to confirm HSV and whether it was HSV1 or HSV2.
Her boyfriend has oral hsv-2
Oral HSV2 is extremely rare and it is not clear whether it can be transmitted from that location.
Are you sure about this story?
I am not sure how plausible all this is. I suggest your friend return to the doctor and confirm through blood test the type of HSV they may have and exactly what swab was performed. Does she have genital HSV2?
