A couple months ago I had a casual encounter with a girl. I had protected vaginal sex with her, but I performed unprotected oral sex on her. I am unaware of her STD status so I can't seem to shake this concern. I went and got test for HIV antibody, gonnorrhea, chlamydia, Hep B, Hep C, syphilis, HSV-1 and HSV-2 (IGG test) at the 6 week mark. How likely was my exposure during this encounter? How much can I trust the STD tests at the 6 week mark? Should I get further testing?
