I’m not sure how much more definitive I can be except to say that I think you should believe your 16 week test for HSV 2 that is negative!
1) If you waited 16 weeks, even for a person who has HSV 1 already, that is enough time to seroconvert.
2) I honestly don’t recall the HSV 1 status of those few people who did not seroconvert, sorry. I haven’t had one in about 3 years.
3) In my experience, if the antibody test misses the HSV 2 infection once, it misses it every time. You could try the western blot to give you more reassurance, what do you think about doing that?
5) Ever? Probably, yes but not often and not with a negative HSV 2 IgG.
I think it is very important that you look at the entire picture here – the encounter, which was brief, once and condom protected, and the test results and the lack of lesions. All point to lack of infection.
