I think with 92% certainty, you do not have HSV-2 infection. The IgG test misses 8% of HSV two infections compared to the herpes western blot. It is possible that you had trauma from the sex toy. With the negative swab test that you have obtained and the negative IgG test at 12 weeks, I think that HSV-2 infection is highly unlikely for you.
As you may know, the HSV one antibody test misses 30% of infections so I am uncertain about that result. If you feel that you need greater certainty, you can obtain the herpes Western blot and that can be done both through me or through your own provider in combination with the University of Washington. You can obtain that kit at 206-685-6066.
