Freaked: You are correct the concentration of HIV is in the cervico-vaginal secretions and very faint in the vaginal secretions however even consumption of the cervico-vaginal secretion is not the right mechanism for HIV transmission.
Acquiring HIV from oral sex is only applicable if blood contact is in the picture.
The reason few experts say oral is low risk cuz theoretically it's possible but practically it needs a few criterion which is impossible to attain.
Bassist1230: You did not acquire HIV by this incidence, you're in the clear. move on !
Thanks. It means a lot to me that you answered. I think I can finally lay my fears to rest.
Take a look at this rist chart...Oral performed on a woman is about the safest form of sex their is! You are fine!

Your 6 to 10 week test is conclusive, you don't have HIV. Having oral sex with your girlfriend is also a lower risk activity. Although HIV is present in vaginal secretions, the virus (which is VERY unlikely that she would have it), resides more in the secretions near the cervix, which if you can reach with your tongue, is quite a darn feat!
Maybe I should add that I fingered her quite often. But I heard there was no risk in that.
