Calm down, you're not at risk.
Coming into contact with an HIV's bodily fluids does not give you HIV. It must enter your bloodstream. I can't imagine that happening, based on what you said you did and what happened.
Secondly (just to clear up something in another post), saliva does not contain an enzyme that inhibits the virus. In fact, HIV lives in small quantities in saliva. The stomach, however, contains acids that kill the virus. This question comes up constantly with regard to oral sex. Is it then safe to swallow cum from an HIV+ guy? Hardly. Remember, there's a long way between the dick and stomach.
Just to clarify, averageguy. I checked several different legitimate sites that describe saliva's inhibitor potential before posting that. Since I'm not an expert on the topic, I checked sources before giving information. I didn't mean to give the impression that saliva completely inhibits HIV, and I did say that it "can" inhibit, but that it's still possible to contract it orally.
The sources I checked are listed below.
Copy of article from the CDC:
http://www.cdc.gov/mmwr/preview/mmwrhtml/00048364.htm
"Exposure to saliva uncontaminated with blood is considered to be a rare mode of HIV transmission for at least five reasons: 1) saliva inhibits HIV-1 infectivity (4 ); 2) HIV is infrequently isolated from saliva (5); 3) none of the approximately 500,000 cases of AIDS reported to CDC have been attributed to exposure to saliva; 4) levels of HIV are low in the saliva of HIV-infected persons, even in the presence of periodontal disease (6); and 5) transmission of HIV in association with kissing has not been documented in studies of nonsexual household contacts of HIV-infected persons (7). However, rare bite-related instances of HIV transmission from exposure to saliva contaminated with HIV-infected blood have been reported (8,9)."
Public Health Agency of Canada (taken from another article):

"Saliva that does not contain blood presents no potential for transmission, as research has shown that an enzyme in saliva inhibits HIV. In general, the mouth and throat are well defended against HIV: the oral mucosal lining contains few of the cells that are the most susceptible to HIV.28 Other research notes that saliva contains several HIV inhibitors, such as peroxidases and thrombospondin-1, and that the hypotonicity of saliva disrupts the transmission of infected leukocytes (white blood cells).29"

thebody.com (which is more cautionary as to not relying on saliva to be a barrier):
http://www.thebody.com/Forums/AIDS/SafeSex/Archive/TransmissionSexual/Q99072.html
"The saliva of infected people contains little to no virus, and the virus that is found in saliva is often inactive (not infectious). Studies have found that a protein in saliva inactivates HIV (up to 90% of virus was inactivated in one test tube study) and other factors that may contribute to the noninfectious quality of saliva. This is why transmission through kissing or receiving oral sex doesn't seem to occur.
This does not mean that saliva will PROTECT you from infection. While the proteins in saliva may reduce the risk of transmission to a person performing oral sex (it may explain the low-risk nature of oral sex), saliva does not serve as a barrier to HIV transmission during oral sex. People can still be infected when performing oral sex, even though the risk is much lower than vaginal or anal sex."
