oralsex

Yes, it is possible for either partner to become infected with HIV
through performing or receiving oral sex. There have been a few
cases of HIV transmission from performing oral sex on a person
infected with HIV. While no one knows exactly what the degree of risk
is, evidence suggests that the risk is less than that of unprotected
anal or vaginal sex.

If the person performing oral sex has HIV, blood from their mouth may
enter the body of the person receiving oral sex through

the lining of the urethra (the opening at the tip of the penis);
the lining of the vagina or cervix;
the lining of the anus; or
directly into the body through small cuts or open sores.
If the person receiving oral sex has HIV, their blood, semen (cum),
pre-seminal fluid (pre-cum), or vaginal fluid may contain the virus.
Cells lining the mouth of the person performing oral sex may allow HIV
to enter their body.

The risk of HIV transmission increases

if the person performing oral sex has cuts or sores around or in their
mouth or throat;
if the person receiving oral sex ejaculates in the mouth of the person
performing oral sex; or
if the person receiving oral sex has another sexually transmitted
disease (STD).
Not having (abstaining from) sex is the most effective way to avoid HIV.

If you choose to perform oral sex, and your partner is male,

use a latex condom on the penis; or
if you or your partner is allergic to latex, plastic (polyurethane)
condoms can be used.
Studies have shown that latex condoms are very effective, though not
perfect, in preventing HIV transmission when used correctly and
consistently. If either partner is allergic to latex, plastic (polyurethane)
condoms for either the male or female can be used. For more
information about latex condoms, see "Male Latex Condoms and
Sexually Transmitted Diseases."

If you choose to have oral sex, and your partner is female,

use a latex barrier (such as a natural rubber latex sheet, a dental dam
or a cut-open condom that makes a square) between your mouth and
the vagina. A latex barrier such as a dental dam reduces the risk of
blood or vaginal fluids entering your mouth. Plastic food wrap also
can be used as a barrier.
If you choose to perform oral sex with either a male or female partner
and this sex includes oral contact with your partners anus (analingus
or rimming),

use a latex barrier (such as a natural rubber latex sheet, a dental dam
or a cut-open condom that makes a square) between your mouth and
the anus. Plastic food wrap also can be used as a barrier.
If you choose to share sex toys with your partner, such as dildos or
vibrators,
each partner should use a new condom on the sex toy; and
be sure to clean sex toys between each use.
