Sex Extra: How can HIV be transmitted during oral sex?

About SEX

Sex refers to the male and female duality of biology and reproduction. Unlike organisms that only have the ability to reproduce asexually, sexed male and female pairs have the ability to produce offspring through meiosis and fertilization. The two sexes attract one another and communicate their readiness to procreate through differences in their biology.An organism's sex category reflects its biological reproductive function rather than its sexuality or other behavior. The female sex is defined as the one which produces the larger gamete and which typically bears the offspring. In contrast, the male sex has a smaller gamete and rarely bears offspring. In some animals, sex may be assigned to specific structures rather than the entire organism. Earthworms, for example, are normally hermaphrodites.

How can HIV be transmitted during oral sex?

HIV (and indeed hepatitis B, which is more infectious) can pose a small risk for both the active (person giving the oral stimulation) and receptive (person receiving oral stimulation) partner.
Transmission from an HIV positive receptive partner to an HIV negative active partner may occur when the active partner gets sexual fluid (semen or vaginal fluid) or blood (from menstruation or a wound somewhere in the genital or anal region) into a cut, sore, ulcer or area of inflammation somewhere in their mouth or throat. The linings of the mouth and throat are very resistant to viral infections such as HIV, so infection is unlikely if they are healthy.
Transmission from an HIV positive active partner to an HIV negative receptive partner is generally believed to be less common. This is because HIV it is normally only present in saliva in very low levels that are not sufficient to cause infection. The only risk in this scenario would be from bleeding wounds or gums in the HIV positive person’s mouth or on their lips, which may transfer blood onto the mucous membranes of the other person’s genitals or anus, or into any cuts or sores they may have. Hepatitis C can also be transmitted this way.
