Oral sex issues: The partner's genital area has an unusual odor?


Hello, doctor.
Recently, I performed oral sex on a male partner, and when he took off his pants, there was a very unpleasant odor.
However, the area outside the glans had a scent of body wash.
After performing oral sex, I also swallowed.
I'm a bit worried about whether I could contract a sexually transmitted infection (STI).
I plan to get tested later.
What kind of STIs could I potentially contract from this? Thank you.

Hello: Many sexually transmitted infections (STIs) are transmitted through sexual contact and the exchange of bodily fluids, which include blood, semen, and vaginal secretions.
Therefore, sexual activities that do not involve the exchange of bodily fluids are considered safe.
The risk levels of various behaviors are as follows:
- No risk: Masturbation
- Low risk: Mutual masturbation, light kissing, mutual rubbing, sexual intercourse with condoms
- Moderate risk: Deep kissing, oral sex, withdrawal method
- High risk: Unprotected sexual intercourse, resulting in wounds or bleeding
Thus, unprotected oral sex is considered moderate risk, and there is a possibility of transmitting various STIs, provided that the partner is infected.
Therefore, if testing is needed, screenings for syphilis, HIV, and oral examinations should be conducted.
If there are any abnormalities in the oral cavity, a medical consultation is advised.
Wishing you good health.

When it comes to oral sex and the associated risks of sexually transmitted diseases (STDs), it is important to understand the potential health implications and the factors that can contribute to the transmission of infections. Your concerns about unpleasant odors and the possibility of contracting an STD after performing oral sex are valid and warrant a thorough discussion.

First, let's address the issue of odors. The presence of an unpleasant smell can be indicative of various conditions, including poor hygiene, infections, or other medical issues. In the case of your partner, the contrasting scents (a foul odor from the genital area and a pleasant scent from the body wash) could suggest that there might be an underlying infection or simply a lack of proper hygiene in the genital region. It is essential for both partners to maintain good hygiene to minimize the risk of infections and to ensure a more pleasant sexual experience.

Now, regarding the risk of STDs from oral sex, it is important to note that while the risk is generally lower compared to vaginal or anal intercourse, it is not zero. Several STDs can be transmitted through oral sex, including but not limited to:
1. Human Immunodeficiency Virus (HIV): Although the risk is lower, it is still possible to contract HIV through oral sex, especially if there are cuts or sores in the mouth.

2. Gonorrhea and Chlamydia: These bacterial infections can infect the throat and may not always present symptoms, making them easy to overlook.

3. Syphilis: This infection can be transmitted through direct contact with syphilis sores, which may be present on the genital area.

4. Herpes Simplex Virus (HSV): Oral herpes (typically HSV-1) can be transmitted to the genital area through oral sex, and vice versa.

5. Human Papillomavirus (HPV): Certain strains of HPV can lead to oral and throat cancers, and they can be transmitted through oral sex.

Given that you performed oral sex and ingested some fluids, it is wise to be cautious. If your partner has an undiagnosed infection, there is a possibility that you could contract an STD. Symptoms may not appear immediately, and some infections can remain asymptomatic for extended periods. Therefore, it is advisable to get tested for STDs, especially if you notice any unusual symptoms in the days or weeks following the encounter.

In addition to testing, it is also important to communicate openly with your partner about sexual health. Encourage them to get tested as well, as this can help both of you understand your health status and reduce the risk of transmission in the future.

To summarize, while the risk of contracting an STD from oral sex is lower than from other forms of sexual activity, it is still present. The unpleasant odor you experienced could be a sign of an underlying issue, and it is essential to prioritize both your health and your partner's health by getting tested. Regular screenings and open communication about sexual health are key components in maintaining a healthy sexual relationship. If you have further concerns or experience any symptoms, do not hesitate to consult a healthcare professional for personalized advice and treatment options.
