The risk of contracting infections through oral sex?


Doctor, I had oral sex with a guy today, and there was contact only during ejaculation, lasting less than ten seconds.
About two hours later, when I urinated at home, I felt a stinging sensation.
Could this be due to dehydration causing urethritis? Is this normal? Also, what other health issues can arise from oral sex? Thank you for your explanation, doctor.

Gonorrhea can also be transmitted through oral sex, so if you have symptoms, it is important to see a urologist for an examination.

When it comes to oral sex and the potential risks associated with it, particularly regarding urological concerns and infections, it’s essential to understand the various factors at play. Oral sex can indeed pose risks for sexually transmitted infections (STIs), but the likelihood of transmission depends on several variables, including the presence of cuts or sores in the mouth, the health status of both partners, and the specific infections involved.

In your case, experiencing a stinging sensation while urinating shortly after receiving oral sex could be attributed to several factors. One possibility is dehydration, which can lead to concentrated urine that may irritate the urethra, causing discomfort. However, it’s also important to consider the potential for an STI, especially if the partner had any infections that could be transmitted through oral sex. Common STIs that can be transmitted this way include gonorrhea, chlamydia, syphilis, and herpes.
If the partner had any oral lesions, infections, or was known to have an STI, the risk of transmission increases. Even if there were no visible signs, many STIs can be asymptomatic. Therefore, if you are experiencing symptoms such as burning during urination, it is advisable to consult a healthcare provider for appropriate testing and evaluation. They may recommend a urinalysis and STI screening to rule out any infections.

Regarding the general risks associated with oral sex, it’s important to note that while the mouth is less likely to transmit infections compared to vaginal or anal intercourse, it is not without risk. Oral sex can lead to infections such as:
1. Gonorrhea and Chlamydia: These can infect the throat and can be transmitted to the urethra during oral sex.

2. Syphilis: This can be transmitted through direct contact with syphilitic sores, which may be present in the genital area or mouth.

3. Herpes Simplex Virus (HSV): Oral herpes can be transmitted to the genital area through oral sex, leading to genital herpes.

4. Human Papillomavirus (HPV): Certain strains of HPV can be transmitted through oral sex and are associated with oropharyngeal cancers.

5. HIV: While the risk is lower compared to other forms of sexual activity, oral sex can still pose a risk for HIV transmission, especially if there are cuts or sores in the mouth.

To minimize the risks associated with oral sex, consider the following precautions:
- Use Barriers: Dental dams or condoms can significantly reduce the risk of STI transmission during oral sex.

- Maintain Oral Hygiene: Good oral hygiene can help reduce the risk of infections. Avoid oral sex if you have cuts, sores, or infections in your mouth.

- Regular STI Testing: Regular screenings for STIs can help catch infections early and reduce the risk of transmission to partners.

- Communication: Discuss sexual health openly with partners, including STI status and any symptoms.

In conclusion, while the discomfort you experienced could be due to dehydration, it is crucial to remain vigilant about potential STIs, especially after engaging in sexual activities. If symptoms persist or worsen, seeking medical advice is the best course of action. Regular check-ups and open communication with partners about sexual health can help mitigate risks associated with oral sex and enhance overall sexual health.
