Unprotected oral sex


Hello, doctor.
I have phimosis and there is a broken area on my foreskin that is red.
After a sex worker performed oral sex on me for 5 minutes without a condom and then we had protected intercourse, my foreskin became more swollen and the broken area worsened.
My hands also feel numb.
I would like to ask how high is the risk of contracting a sexually transmitted infection or bacteria in this situation?

Hello: Wounds are susceptible to common bacterial infections, especially since saliva contains bacteria.
As for sexually transmitted infections, you can refer to https://www.cdc.gov.tw/Category/ListContent/BcwrIdNHhlziwBeJq9UJ7Q?uaid=1TI7GoOkq9v7X-lr2QtYog.
Oral sex is considered a moderate risk.
Wishing you good health.

When it comes to the risk of sexually transmitted infections (STIs) and other bacterial infections from unprotected oral sex, especially in the context of your situation, there are several important factors to consider.
Firstly, it is crucial to understand that STIs can be transmitted through oral sex, and the risk is influenced by various factors including the presence of cuts or sores, the type of sexual activity, and the overall health of both partners. In your case, having a broken or irritated area on the foreskin increases the risk of infection. This is because any break in the skin can serve as an entry point for pathogens, including bacteria and viruses.

1. Risk of STIs: Certain STIs, such as herpes, syphilis, gonorrhea, and chlamydia, can be transmitted through oral sex. The risk is higher if the oral partner has an active infection, especially if they have sores or lesions in their mouth. Since you mentioned that you had unprotected oral sex with a sex worker, there is a potential risk of contracting an STI, particularly if they were not screened or treated for STIs.

2. Bacterial Infections: The presence of broken skin can also increase the likelihood of bacterial infections. If the oral sex was performed without protection, bacteria from the mouth can enter through the broken skin on your foreskin, potentially leading to infections such as cellulitis or other skin infections.
3. Symptoms: The symptoms you are experiencing—redness, swelling, and increased severity of the broken skin—could indicate an infection. It is essential to monitor these symptoms closely. If they worsen or do not improve, it is advisable to seek medical attention promptly.
4. Testing and Diagnosis: Given your concerns and the potential exposure, it would be prudent to get tested for STIs. Many STIs can be asymptomatic, meaning you might not show symptoms even if you are infected. Regular testing is recommended for sexually active individuals, especially after potential exposure to STIs.

5. Prevention: Moving forward, consider using protection during oral sex, such as condoms or dental dams, to reduce the risk of STIs. Additionally, maintaining good oral hygiene and avoiding oral sex if there are any cuts or sores in the mouth can help minimize risks.

6. Consultation with a Healthcare Provider: It is highly recommended to consult with a healthcare provider or a urologist. They can perform a thorough examination, provide appropriate tests for STIs, and offer treatment options if necessary. They can also address any concerns you may have regarding your symptoms and overall sexual health.

In conclusion, while the risk of STIs and bacterial infections from unprotected oral sex is present, especially with broken skin, taking proactive steps such as testing and consulting with a healthcare professional can help manage your health effectively. Remember, early detection and treatment are key to maintaining sexual health.
