This is what the doc said in early 2005 regarding cunnilingus.
"STD transmission from female genitals to a person's mouth by cunnilingus has never been shown to occur, to my knowledge. Granted, this hasn't been studied much--but the reason it hasn't been studied is that it seems to be too low risk to make it worthwhile to do any research. It stands to reason there is a risk of herpes transmission, if the woman has genital HSV infection, and perhaps HPV (but HPV of the mouth never causes symptoms anyway). Syphilis also clearly is possible but rare. If there is some tiny risk of chlamydia, gonorrhea, syphilis, or HIV, the risk is too small to worry about (or for you to be tested). The symptoms you are experiencing almost surely are unrelated to the exposure you describe, except indirectly through anxiety.
As I have written many times in this forum, when a person suspects his or her own symptoms are due to anxiety, usually they are right. But since HIV is what you seem to be worried about, get tested; the negative result probably will be more reassuring than anything I can say. (Search the forum for "time to positive HIV test for many other threads about when to be tested.)

This answer can be found in the STD forum and is entitled "what can be transmitte orally?" posted initially by forum user dsc1212 on 08/09/2005.
You can also type in "time to test positive HIV" and look for the answer there.
Good luck!

In other terms: these vaginal secretion are really able to infect?
If the answer is yes, I think that licking vaginal secretions is like lickin blood.
And, if the answers is yes, who could make a cunnilingus without any fright?
