2. Should I accept the 8 week iGG antibody blood test as conclusive?
Yes, because the contact you had was risk free
3. In the off chance Vaginal secretions or saliva were involved, would this increased exposure change your point of view?
It would noht
4. I still sometimes feel the contracting/throbbing sensation throughout my groin, is this a red flag?
Not of herpes! Or any other sexually transmitted infection, no.
