The San Fransico Dept of Health list cunninglus as have no HIV risk, not even as possilbe or unknown. I have seen various
web sites on Aids/STD prevention use this infomation. So if they are saying that cunninglus does not have even a possilbe or unknown risk, they must have some definate proof, what is it??? Otherwise they are being irresponsible, which I cannot imagine since they are at ground zero of AIDS in the U.S and have the most experience dealing with.
