The possibility of infection from oral sex?


Hello Doctor, I had unprotected oral sex with a partner at the end of January, but that was the only encounter, and I did not touch her private areas.
She also did not touch her own private areas.
However, at the end of March, she informed me that she suspected she had genital warts (she does not have any warts in her mouth).
I would like to ask if it is possible for me to be infected with genital warts in this situation.
Additionally, I have had pearly penile papules on my corona and frenulum since childhood.
Recently, I have been very worried and am unsure if these white bumps could be a symptom of genital warts.
I kindly request your clarification.
Thank you very much!

More Info


Oral sex can indeed transmit Human Papillomavirus (HPV), which is a sexually transmitted infection (STI) known for its association with various health issues, including genital warts and certain cancers. The risk of transmission during oral sex is present, especially if there are any cuts or abrasions in the mouth or throat, as HPV can enter through these openings.
In your case, since you engaged in unprotected oral sex with a partner who later reported having genital warts (often referred to as "cauliflower" lesions), there is a possibility that you could have been exposed to HPV. However, the likelihood of developing visible symptoms such as warts in the mouth or throat depends on several factors, including your immune system's response to the virus and whether you were infected at all.

HPV is categorized into low-risk and high-risk types. Low-risk types, such as HPV 6 and 11, are primarily associated with genital warts, while high-risk types, such as HPV 16 and 18, are linked to cancers, including cervical, anal, and oropharyngeal cancers. The types of HPV that cause genital warts do not typically lead to cancer, but they can still be transmitted through oral sex.

Regarding your concern about the white bumps you mentioned, it is essential to differentiate between various conditions. The "pearly penile papules" you described are common and usually harmless. They are not caused by HPV and are considered a normal anatomical variation. However, if you notice any changes in the appearance of these bumps or if you develop new lesions, it is crucial to consult a healthcare provider for an accurate diagnosis.

If you are worried about potential HPV infection, it is advisable to seek medical evaluation. A healthcare professional can perform a thorough examination and may recommend testing for HPV, especially if you have symptoms or concerns about your sexual health. Regular screenings and check-ups are essential for early detection and management of any STIs.

In terms of prevention, using barriers such as condoms or dental dams during oral sex can significantly reduce the risk of HPV transmission, although they do not eliminate the risk entirely. Vaccination against HPV is also an effective preventive measure, particularly for individuals who have not yet been exposed to the virus.

In summary, while oral sex can transmit HPV, the actual risk of developing symptoms or complications varies. If you have concerns about your sexual health or potential HPV infection, it is best to consult a healthcare provider for personalized advice and management. Regular screenings and preventive measures can help maintain your health and reduce the risk of transmission.
