Hi,
your risk from hiv in the scenario you describe is extremely low, and in my opinion does not warrant testing. I say this based on the following -
- there is an insufficient quantity of the hiv virus present in saliva to cause infection (this is why kissing is considered safe).
- the cut you describe does not sound severe enough to be a viable route of transmission (consider that many medical professionals have concluded that minor cuts on the fingers are not viable entry points for hiv during fingering for example - an acitivity which involves vaginal fluids, which have much more of the virus than saliva). If it was not bleeding, then this suggests that the wound is not really fresh. But I cannot confirm this since it is difficult to judge how bad your cut was.
- it is very unlikely that any blood was present in her mouth at the time
- if you had protected sex, and the condom did not break, infection is pretty much impossible.
Try not to worry, but just take a test to put your mind at ease, but remember this must be at least three months after the episode for it to be accurate. Chances are, she wasn't hiv anyway.You'll see that the advisers, who are experts in the field, assert that the only worrisome scenarios for hiv are unprotected vaginal, anal and much more rarely, oral sex, as well as needle sharing, breast feeding and needlestick accidents. Your scenario is not included. Good luck, but I strongly doubt you'll need it.
