You may be having a herpes outbreak. The only thing I know of that you can get from unprotected oral sex is herpes. The other tests should come back fine. Please use a condom every single time with every single sex act. If this girl was willing to not use a condom with you then she is that way with everyone. You already have herpes so you do not want to get anything else.
