Unprotected oral sex and sexually transmitted infections (STIs)?

Hello Doctor, eight days ago, I impulsively engaged in unprotected oral sex with a stranger and kissed her (without tongue contact).
Yesterday, I noticed a white bump on my penis.
I have already consulted a urologist who believes it is a pimple.
During the diagnosis, I asked him about the risk of sexually transmitted infections (STIs) from unprotected oral sex and kissing.
Regarding HIV, as far as I know, the infection rate is extremely low but not zero.
However, when I asked him about the likelihood of contracting other STIs, he confidently stated that the risk is low because the oral cavity is an unfriendly environment for bacteria.
From my research, I found that the transmission rate of other STIs through oral sex can actually be higher.
Therefore, I would like to ask Dr.
Du's opinion: Is the risk of contracting other STIs from unprotected oral sex and kissing high? Which ones are more likely? (For example, since it has been eight days, can I rule out gonorrhea?) I plan to get tested, and could you please advise me on which tests to undergo?

Hello: The risk of contracting sexually transmitted infections (STIs) from unprotected oral sex is similar to that from unprotected vaginal intercourse, with the key factor being the partner involved.
Possible infections include HIV, human papillomavirus (HPV), gonorrhea, and syphilis.
In your case, the most concerning STI with a latency period of up to three months is HPV, and in some individuals, it can extend up to a year.
Therefore, you should get tested three months later.
If there are any issues currently, you should seek medical attention.
Thank you for your inquiry.

Engaging in unprotected oral sex does carry a risk of sexually transmitted infections (STIs), and it's important to understand the nuances of these risks, especially when considering various sexual practices such as oral sex and kissing.
Firstly, it's essential to recognize that while the risk of HIV transmission through oral sex is significantly lower compared to vaginal or anal sex, it is not zero. Factors that can increase the risk of HIV transmission during oral sex include the presence of cuts or sores in the mouth, gum disease, or the presence of blood. The general consensus is that the risk of HIV from oral sex is low, but it is still advisable to take precautions, such as using condoms or dental dams.

When it comes to other STIs, the risk of transmission through oral sex can vary. For instance, infections such as gonorrhea and chlamydia can be transmitted through oral sex, particularly if one partner has an active infection in the genital area. The transmission rates for these infections can be higher than for HIV, especially if there are mucosal abrasions or other factors that facilitate the entry of pathogens.
In your case, the presence of a white bump on the penis could be concerning, and while your urologist suggested it might be a sebaceous cyst or a similar benign condition, it is crucial to monitor any changes and seek further evaluation if necessary. The fact that you engaged in unprotected oral sex does warrant STI testing, especially for gonorrhea, chlamydia, syphilis, and herpes, as these infections can sometimes be asymptomatic.

Regarding your question about the timeline for testing, it is important to note that different STIs have varying "window periods" for accurate testing. For example, testing for gonorrhea and chlamydia can typically be done about a week after exposure, while HIV testing is most reliable after 2-4 weeks, with a follow-up test at 3 months for conclusive results. Syphilis testing can also be done after a few weeks, but it is best to consult with your healthcare provider for personalized advice based on your specific situation.

In summary, while the risk of HIV from oral sex is low, the risk of other STIs is more significant and should not be overlooked. It is advisable to undergo testing for common STIs, especially if you have engaged in unprotected sexual activities. Regular testing and open communication with sexual partners about STI status are key components of maintaining sexual health. If you have any further concerns or symptoms, do not hesitate to reach out to a healthcare professional for guidance and support.
