Is it possible that hsv 2 can be on my lip? Could I get it on my vagina by touching the sore then touching myself? How long does it live onmy fingers

Herpes oral, genital. If you have oral herpes, probably it is HSV1, not HSV2. Whichever type you have, auto-inoculation (transfer of infection to a new body area) is very rare except during the initial HSV infection. Even then it is uncommon. Don't worry how long the virus may "live on your fingers"; it doesn't matter. You probably could not transmit it to your genital area even if you tried. No worries!
