While it is agreed that oral sex is a very much lower risk activity—in terms of HIV-infection risk—than vaginal and anal sex, HIV can be transmitted through both insertive and receptive oral sex,[16] when there is contact between semen and the mucous membranes of the mouth. The risk of infection from a single encounter is small, but it increases with frequency of activity according to binomial probability theory. Transmission risk may be elevated in the case of open sores on the genitals and/or mouth, or significant gum disease or bleeding, i.e., when there is direct contact between semen or saliva and breaks in the skin or surface of the mouth.
The problem is the only infection study that has been done between oral sex and HIV is from research done in the early 90's where HIV posative gay men stayed that they only participated in oral sex. HIV needs contact with red blood cells within a few seconds. Salivia kills the HIV cells slowly (slowly as in a mater of seconds).
Honestly you have more to worry about from chlamydia genital warts/herpes then from HIV.
