There has been some discussion in this newsgroup of the UC Berkeley 
studying linking oral sex and HIV transmission.  The following article

"Study Uncovers New Information on HIV Spread"

New analysis of HIV infections in San Francisco shows that the 
risk of HIV infection from oral intercourse between men may be greater 
than widely believed.

Berkeley scientists reported Oct. 3 that men who participated in oral
intercourse--specifically men who engaged in receptive oral
intercourse--increased their chances of infection.

Epidemiologist Michael Samuel, a doctoral candidate in the School of
Public Health, said his data both confirm the ``paramount importance
of receptive anal intercourse'' as a risk factor for HIV infection, and
suggest that ``oral receptive intercourse, often reported to be of no
risk, may also be risky.''

Analysis of four types of sexual practices (receptive and insertive
anal intercourse, and receptive and insertive oral intercourse) reported
in the study showed:

--more than 50 percent of the 82 men who became infected engaged in all
  four practices;

--34 percent of the infected men did not engage in anal receptive 
  intercourse, but did participate in at least one of the other three
  behaviors;

--17 percent of the infected men reported only oral intercourse, either
  receptive or insertive.

Elevated risk was also associated with a douche or enema before anal
intercourse.  Regardless of sexual practice, risk of infection rose with
the number of partners.
