Herpes doesn't spread this way. Herpes is spread via direct skin to skin contact - mouth to mouth, mouth to genital, or genital to genital, and requires some friction to spread.
You weren't at risk for any STD from this, and no testing is necessary.
Yes, even then. STDs die rapidly once exposed to air, and herpes doesn't spread via saliva unless it comes into contact with herpes virus on the lips. Did she have a sore present? I'm assuming she didn't because you would have mentioned that.
Have you ever tested for hsv1? About half the adult population has it, and 90% won't ever get symptoms, so you could easily have it and not know it. If you already have it, you can't get it again. Ask your doctor for a type specific IgG herpes blood test.
For clarification - if someone performed oral sex on you and you got genital herpes from that, it would be genital herpes type 1. The number indicates the strain of the virus, not the location of the infection on your body.
Really, you had no risk, and you don't have to worry.
