What medical experts say about intimacy and health risks
By David Nthua, January 21, 2026In Kenya and around the world, conversations about intimacy and sexual behaviour are often private, sensitive, and shaped by culture.
One topic that many people wonder about quietly is oral intimacy. Some assume it is completely risk-free, others worry about health, and many simply do not know what experts actually say.
So what do science and medical guidance tell us? Can oral intimacy affect your health, and are there reasons some health professionals recommend caution?
In this story, we will get to know why medical experts have for a long time issued caution on oral intimacy.
Risk of infection
Health organisations that study sexually transmitted infections (STIs) are clear that oral intimacy is not completely free of risk.
According to the Centers for Disease Control and Prevention (CDC) in the United States, “Genital fluids and sores in the mouth or on the genitals can transmit infections during oral intimacy.”
The CDC explains that infections such as gonorrhoea, chlamydia, syphilis and human papillomavirus (HPV) can be passed through oral-genital contact.
This means that oral contact is not automatically safe, especially if one partner has an untreated infection.
The likelihood of transmission varies by infection, but the possibility is real enough that health authorities include oral behaviours in public health advice.
HPV and throat health
One infection that receives particular attention in research is HPV. According to the World Health Organization (WHO), certain strains of HPV are linked to cancers of the mouth and throat, although these cases are rare and not all HPV infections lead to cancer.
The WHO explains that HPV can be passed through intimate contact, and vaccination and safe practices reduce risk.
HPV is common, and most infections do not cause severe disease, but because of its link to some throat cancers, many health experts include it in discussions about oral sexual contact. Vaccination for HPV and regular health check-ups can reduce risk.
Sexual health professionals also stress clear communication between partners. According to sexual health educator Maureen Morales, writing for Healthline, “Any intimate contact carries some potential for infection.
Talking openly about STI testing, health history, and protection makes decisions safer.” Morales’s guidance is rooted in reducing risk through information, not in discouraging intimacy.
Open communication can also reduce anxiety and ensure both partners are comfortable and consensual in their choices.
When discussing safer intimacy, many public health sources recommend barrier methods. The CDC notes that using barriers such as condoms or dental dams during oral contact can significantly reduce the chance of transmitting infections.
Barriers are thin, flexible materials placed between the mouth and genital area. They act as a physical block to fluids and sores that may carry infections. While not used by everyone, they are a recognised method to lower risk, especially when partners are not in a long-term monogamous relationship or have an unknown health status.
Doctors and health educators recommend special caution in certain situations:
- When either partner has a known or suspected STI
- When either partner has open sores, cuts, or inflammation in the mouth
- When one partner has not been tested recently
In these scenarios, waiting to seek medical advice, using barriers, and doing regular health screening can reduce risks.
Health professionals also highlight that safe sexual behaviour is not only about physical health but also about emotional wellbeing.
Morales writes that “Consent and comfort between partners is as important as physical safety.” This means both parties should agree freely and feel comfortable discussing boundaries and concerns without pressure.
Feeling pressured into any form of intimacy can have emotional consequences, and consent is a core principle in healthy relationships.
It is important to be clear about what science does not support. No major health organisation says that all intimate contact must be avoided.
Instead, they encourage informed choices based on understanding risk and reducing it where possible.
Avoiding fear-based messages, credible sources focus on education, prevention, and communication.
