You were not at risk for HIV. You used protection for penetration, and condoms work to protect you.
HIV is not transmitted by getting blood in your mouth, or by swallowing blood. You do not need to test for HIV.
We understand that she has tested positive. However, there can be no risk attributed to this event as stated by CurfewX, condoms were protecting you. Infected blood can't crawl up through the condom in to your urethra.
Oral sex is 'no' risk not low risk, there has never been concrete data on transmission through that route. Also, there has been lot of recent studies to support the fact that oral sex is not a risk.
I second CurfewX. You don't need to test, you were never at risk.
