Did you read the post you are responding to? That's what it says. Hep B is found in saliva, but there are no documented cases where oral sex has transmitted it.
You need to talk to your doctor about your anxiety. In June, you got oral sex and had protected anal sex. Your risks are very low for syphilis, HPV and herpes.
You had no risk for any hepatitis, gonorrhea, chlamydia, HIV, or anything else.
I have no idea why you are so anxious, but just test and let it go. Get the peace of mind from testing, and move on from this.
Talk to your doctor about vaccines for Hep A and B, too. And your anxiety - you need help with this.
