ANSWER:

While oral sex is realtively a low risk behaviour, yes, it is possible to contract the HIV virus by having oral sex with an infected female, particularly where there is broken tissue or sores in the mouth of the person performing oral sex. Whenever there is a possibility that infected bodily fluids can be exchanged, there is the potential of HIV transmission. That said, the risk of transmission via oral sex is lower than from penetrative vaginal or anal sex.

The low risk of becoming infected with HIV from oral sex can be reduced further by using latex condoms. Plastic food wrap, a condom cut open, or a dental dam can serve as a physical barrier to prevent transmission of HIV and many other STDs.
