"Oral sex is still a risk, preventing the sexual transmission of HIV, the virus that causes AIDS and what you should know about oral sex.\n\nCDC / HIV AIDS UPDATE From The Centers for Disease Control and Prevention\nOral Sex Is Not Considered Safe Sex Like all sexual activity, oral sex carries some risk, particularly when one partner or the other is known to be infected with HIV, when either partner\u2019s HIV status is not known, and/or when one or the other partner is not monogamous or injects drugs. Numerous studies have demonstrated that oral sex can result in the transmission of HIV and other sexually transmitted diseases (STDs). Abstaining from oral, anal, and vaginal sex all together or having sex only with a mutually monogamous, uninfected partner are the only ways that individuals can be completely protected from the sexual transmission of HIV.  Oral Sex is a Common Practice Oral sex involves giving or receiving oral stimulation (i.e. sucking or licking) to the penis, the vagina, and/or the anus. Fellatio is the technical term used to describe oral contact with the penis. Cunnilingus is the technical term which describes oral-vaginal sex. Anilingus (sometimes called \u201Crimming\u201D) refers to oral-anal contact. Studies indicate that oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents. Although there are only limited national data about how often adolescents engage in oral sex, some data suggest that many adolescents who engage in oral sex do not consider it to be sex; therefore they may use oral sex as an option to experience sex while still, in their minds, remaining abstinent. Moreover, many consider oral sex to be a safe or no risk sexual practice. In a recent national survey of teens conducted for The Kaiser Family Foundation, 26% of sexually active 15 to 17 year olds surveyedresponded that one \u201Ccannot become infected with HIV by having unprotected oral sex\u201D, and an additional 15% didn\u2019t know whether or not one could become infected in that manner.  Oral Sex and the Risk of HIV Transmission The risk of HIV transmission from an infected partner through oral sex is much smaller than the risk of HIV transmission from anal or vaginal sex. Because of this, measuring the exact risk of HIV transmission as a result of oral sex is very difficult. In addition, since most sexually active individuals practice oral sex in addition to other forms of sex, such as vaginal and/or anal sex, when transmission occurs, it is difficult to determine whether or not it occurred as a result of oral sex or other more risky sexual activities. Finally, several co-factors can increase the risk of HIV transmission through oral sex, including: oral ulcers, bleeding gums, genital sores, and the presence of other STDs. When scientists describe the risk of transmitting an infectious disease, like HIV, the term \u201Ctheoretical risk\u201D is often used. Very simply, \u201Ctheoretical risk\u201D means that passing an infection from one person to another is possible, even though there may not yet be any actual documented cases. \u201CTheoretical risk\u201D is not the same as likelihood. In other words, stating that HIV infection is \u201Ctheoretically possible\u201D does not necessarily mean it is likely to happen\u2014only that it might. Documented risk, on the other hand, is used to describe transmission that has actually occurred, been investigated, and documented in the scientific literature. \n\n\n\n\n\n\nTheoretical and Documented Risk of HIV Transmission During Oral-Penile Contact\n\n\n\n\n\nTheoretical Risks\n\n\n\n\n\nIn fellatio, there is a theoretical risk of transmission for the receptive partner (the person who is sucking) because infected pre-ejaculate (\"pre-cum\") fluid or semen can get into the mouth. For the insertive partner (the person who is being sucked), there is a theoretical risk of infection because infected blood from a partner's bleeding gums or an open sore could come in contact with a scratch, cut, or sore on the penis.\n\n\n\n\n\nDocumented Risks\n\n\n\n\nAlthough the risk is many times smaller than anal or vaginal sex, HIV has been transmitted to receptive partners through fellatio, even in cases when insertive partners didn't ejaculate (\"cum\").\n\n\n\n\n\nTheoretical and Documented Risk of HIV Transmission During Oral-Vaginal Contact\n\n\n\n\n\nTheoretical Risks\n\n\n\n\nCunnilingus carries a theoretical risk of HIV transmission for the insertive partner (the person who is licking or sucking the vaginal area) because infected vaginal fluids and blood can get into the mouth. (This includes, but is not limited to, menstrual blood). Likewise, there is a theoretical risk of HIV transmission during cunnilingus for the receptive partner (the person who is having her vagina licked or sucked) if infected blood from oral sores or bleeding gums comes in contact with vulvar or vaginal cuts or sores.\n\n\n\n\nDocumented Risks\n\n\n\n\nThe risk of HIV transmission during cunnilingus is extremely low compared to vaginal and anal sex. However, there have been a few cases of HIV transmission most likely resulting from oral-vaginal sex.\n\n\n\n\u00A0\nTheoretical and Documented Risk of HIV Transmission During Oral-Anal Contact\n\n\n\n\nTheoretical Risks\n\n\n\nAnilingus carries a theoretical risk of transmission for the insertive partner (the person who is licking or sucking the anus) if there is exposure to infected blood, either through bloody fecal matter (bodily waste) or cuts/sores in the anal area. Anilingus carries a theoretical risk to the receptive partner (the person who is being licked/sucked) if infected blood in saliva comes in contact with anal/rectal lining.\n\n\n\nDocumented Risks\n\n\n\nThere has been one published case of HIV transmission associated with oral-anal sexual contact.\n\n\n\n\n\n\n\n\n\n\nOther STDs Can Also Be Transmitted From Oral Sex Scientists have documented a number of other sexually transmitted diseases that have also been transmitted through oral sex. Herpes, syphilis, gonorrhea, genital warts (HPV), intestinal parasites (amebiasis), and hepatitis A are examples of STDs which can be transmitted during oral sex with an infected partner. For more information see Oral Sex and STDs Fact Sheet. Reducing the Risk of HIV Transmission Through Oral Sex The consequences of HIV infection are life-long, life-threatening, and extremely serious. You can lower any already low risk of getting HIV from oral sex by using latex condoms each and every time. For cunnilingus or anilingus, 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. Because anal and vaginal sex are much riskier and because most individuals who engage in unprotected (i.e. without a condom) oral sex also engage in unprotected anal and/or vaginal sex, the exact proportion of HIV infections attributable to oral sex alone is unknown, but is likely to be very small. This has led some people to believe that oral sex is completely safe. It is not.  Source: Centers for Disease Control"^^<http://www.w3.org/2001/XMLSchema#string>
