Penile swelling and redness?


Hello doctor, about a week ago my girlfriend performed oral sex on me.
At the end, I felt pain in the frenulum and the inner side of the foreskin (similar to nerve pain).
There was no pain after an erection.
I checked and didn't see any wounds.
After resting for almost a week, the situation hasn't improved; instead, the entire inner foreskin, the frenulum, and the urethral opening at the tip of the glans have become slightly red and swollen.
I would like to ask if this might be an inflammation and whether I need to seek medical attention, or if it will heal on its own?

When it comes to redness and swelling in the penis, particularly after sexual activity, it is essential to consider several factors that could contribute to these symptoms. Based on your description, it seems you are experiencing discomfort and inflammation in the area, which could be indicative of a few potential conditions.

Firstly, the pain you felt during oral sex, particularly in the frenulum (the band of tissue on the underside of the penis) and the inner foreskin, could be due to friction or irritation. This is not uncommon, especially if there was vigorous activity or if there was a lack of adequate lubrication. The fact that the pain subsided after an erection suggests that it may not be a severe injury but rather a temporary irritation.

However, the development of redness and swelling a week later raises some concerns. Inflammation in the genital area can be caused by several factors, including:
1. Infection: This could be a sexually transmitted infection (STI) such as herpes, gonorrhea, or chlamydia, especially if there were any unprotected encounters. Symptoms of an STI can include redness, swelling, pain, and sometimes discharge.

2. Balanitis: This is an inflammation of the glans (the head of the penis) and can occur due to poor hygiene, irritants, or infections. It can cause redness, swelling, and discomfort.

3. Allergic Reaction: Sometimes, the use of certain lubricants, condoms, or even soaps can lead to an allergic reaction, resulting in inflammation and redness.

4. Friction Injury: If there was significant friction during sexual activity, it could lead to irritation and inflammation, which might take longer to resolve.

Given that your symptoms have persisted for a week without improvement, it is advisable to seek medical attention. A healthcare professional can perform a thorough examination, possibly including tests for STIs, and provide appropriate treatment. Early intervention is crucial, especially if an infection is present, as untreated infections can lead to more severe complications.

In the meantime, here are some general recommendations:
- Avoid further irritation: Refrain from any sexual activity until you have been evaluated by a doctor.

- Maintain hygiene: Keep the area clean and dry. Use mild soap and avoid any harsh chemicals or irritants.

- Avoid self-diagnosis: While it might be tempting to look up symptoms online, it’s essential to consult a healthcare provider for an accurate diagnosis and treatment plan.

In conclusion, while some cases of mild irritation may resolve on their own, the persistence of your symptoms suggests that medical evaluation is warranted. Seeking help from a healthcare provider will ensure that you receive the appropriate care and can help prevent any potential complications.
