What are the chances of contracting HIV if you get a blowjob from an?
First, It is not AIDS that spreads. AIDS stands for Acquired Immuno Deficiency Syndrome. The words Immuno Deficiency explain the nature of the disease. i.e. a chronic condition where you lose the ability to fight off secondary diseases (such as TB or even flu). What spreads is retrovirus which causes HIV. AIDS is a chronic condition of HIV. Now, to answer your question, Transmission of HIV is a complicated process. It only spreads through body fluids (Semen and /or Blood in this case) as they provide a gateway to your bloodstream. Oral sex doesn't pose a very great risk of transmission, however the odds are not zero. Saliva contains a lot of enzymes which inhibit the growth of retrovirus. Moreover, the acidic nature of your stomach doesn't provide a suitable environment for the virus to replicate thereby killing the chances of transmission. However, if the person who is performing oral sex, has cuts, sores, or basically anything that might bleed or provide access to bloodstream then the risk of transmission is increased. The performer is at a higher risk of catching the virus than the receiver if the receiver is infected. If the performer is infected, the receiver may or may not be at a high risk. It is usually dependent upon the way in which the two parties indulge. So while the risk is really low (like .04%) it is not zero.
