The lesion concerns me because that is the way herpes presents – with a sore.
HSV does not cause prostatitis, no. It also does not cause testicular pain or stomach pains.
Since your HSV 1 index value suggests a well established HSV 1 infection, this lesion could be due to a longer standing HSV 1 genital infection. Or you could have new HSV 2 infection – the antibody testing was done too soon to detect a new infection.
I would recommend that you repeat the HSV 2 antibody test about 10 weeks from the sexual encounter that you describe. If negative, that’s good news. If you have never had a cold sore, there is no way to know if your HSV 1 infection is oral or genital.
