Wait! There is a lot to unpack here.
1. Do you have herpes? Hsv1 or hsv2 or both? How were you diagnosed?
2. What kind of herpes test did your partner take? Were there index values with his results?
3. What do you mean you never had "full" intercourse? If a penis did not enter a mouth, anus or vagina, the odds that herpes was transmitted is close to zero.
