The Hidden Danger of Oral Sex: Why It Is the Second Highest-Risk Practice for STI Transmission
Did you know that an everyday practice engaged in by 87% of people hides a risk that most tend to ignore? A famous political scandal from the 1990s forever changed the way we understand these encounters and their health consequences. Discover why this misconception persists and what steps you can take to enjoy yourself without exposing yourself to risk.
Although 87% of the population practices oral sex under the false belief that it is a risk-free activity, scientific evidence shows that it is a frequent cause of Sexually Transmitted Infections (STIs). This misconception is largely due to a lack of sex education, but also to a media milestone: in 1998, following the scandal between Bill Clinton and Monica Lewinsky, the idea that fellatio did not constitute "sex" was popularized, unlinking these practices from genital health care and contributing to a subsequent increase in infections.
In medical terms, oral sex includes fellatio, cunnilingus, and anilingus, placing it on the risk spectrum as the second practice with the highest probability of STI transmission, behind only unprotected anal penetration. The danger lies in the fact that bacteria such as gonorrhea, chlamydia, and syphilis, along with viruses like herpes or human papillomavirus (HPV), can infect not only the genitals and anus, but also the mouth and pharynx, almost always presenting asymptomatically.
During fellatio, cunnilingus, or anilingus performed without latex barriers, the transmission of these infections is extremely easy if either person involved carries the pathogen in the genital area or throat. While HIV is difficult to transmit this way because saliva does not carry the virus, the risk increases if there is ejaculation or open wounds. For this reason, professionals recommend not brushing your teeth immediately after oral sex, thereby preventing the creation of gum lesions that could serve as an entry point for microorganisms.
Far from suggesting the cessation of these practices—which bring great benefits to intimacy, self-esteem, and partner satisfaction—the solution lies in proper protection. The use of condoms, dental dams, or latex underwear almost completely eliminates the chances of contagion. However, for those who prefer not to use barrier methods during oral sex, an equally essential preventive alternative exists: getting tested for STIs regularly and keeping up with routine checkups.
