Concerns After Oral Sex: Possible STIs and Symptoms Explained - Urology

Two days after oral sex?


A few days ago, I had unprotected oral sex, and I noticed something at the urethral opening of my partner (it was too dark to see clearly).
The skin on both sides of the urethral opening felt a bit rough.
During oral sex, my head was pushed down forcefully, and two days later, I developed a sore throat with a lot of yellow phlegm and persistent coughing.
It’s possible that the forceful pressure caused an injury to my throat, but the symptoms on my partner's genital area make me suspect whether I might have contracted a sexually transmitted infection (STI) such as gonorrhea, syphilis, or HPV through oral sex.
Given these symptoms, is it possible that I have been infected?

Engaging in unprotected oral sex can raise concerns about sexually transmitted infections (STIs), especially if there are visible abnormalities on the partner's genital area. In your case, the symptoms you are experiencing, such as throat pain and increased mucus production, could potentially be linked to an STI, but they may also be due to other factors.

Firstly, it’s important to understand that oral sex can transmit several STIs, including gonorrhea, chlamydia, syphilis, and herpes. The presence of any lesions or abnormalities on your partner's genital area, such as the lump you mentioned, could indicate an infection that might be transmissible. Gonorrhea and chlamydia are particularly known for causing throat infections when transmitted through oral sex, leading to symptoms like sore throat, increased mucus, and coughing.

The fact that you experienced throat pain and increased phlegm two days after the encounter raises the possibility of an infection. However, it is also essential to consider that throat discomfort can result from physical trauma, especially if there was significant pressure applied during the act. This could lead to irritation or injury to the throat, which might explain your symptoms without the presence of an STI.

In terms of the yellow phlegm, this could indicate a bacterial infection, possibly unrelated to an STI. Yellow mucus often suggests that the body is fighting off an infection, which could be viral or bacterial in nature. If the symptoms persist or worsen, it would be prudent to seek medical attention.

To address your concerns about specific STIs like gonorrhea, syphilis, or HPV (which causes genital warts), it is advisable to get tested. Testing for STIs typically involves a combination of urine tests, blood tests, and throat swabs, depending on the suspected infections. It is recommended to wait at least one to two weeks after potential exposure for accurate testing results, as some infections may not be detectable immediately.

In summary, while your symptoms could be indicative of an STI, they could also be the result of physical trauma or another type of infection. It is essential to consult a healthcare provider who can perform the necessary tests and provide a thorough examination. They can also offer guidance on treatment options if an infection is confirmed. Remember, early detection and treatment are crucial in managing STIs effectively and preventing complications.
