There are red spots near the coronal sulcus?


Hello, there is a red spot in the area near the corona, and after retracting the foreskin completely, there is a slight foul-smelling discharge that feels a bit moist.
It is not painful or itchy to the point of discomfort, just slightly itchy but not enough to scratch.
This started about a week after having sexual intercourse.
What could this indicate?

More Info


The presence of red spots near the corona (the ridge of the glans) can be concerning, especially when accompanied by a slight odor and moisture. Based on the symptoms described, there are several potential causes that could explain these observations.

1. Balanitis: This is an inflammation of the glans penis, which can occur due to various reasons, including poor hygiene, irritants, or infections. The presence of red spots and a slight odor may suggest that there is some irritation or infection present. Balanitis can be caused by yeast infections, bacterial infections, or sexually transmitted infections (STIs).

2. Yeast Infection: A common cause of irritation and redness in the genital area is a yeast infection, particularly if there is an overgrowth of Candida. This can happen due to factors such as antibiotic use, which disrupts the normal flora, or conditions that promote yeast growth, such as diabetes.

3. Sexually Transmitted Infections (STIs): Given that the symptoms began after a sexual encounter, it is important to consider the possibility of STIs. Conditions such as herpes, gonorrhea, or chlamydia can present with symptoms like redness, irritation, and discharge. Even if there is no pain or severe itching, it is crucial to get tested for STIs if there is a possibility of exposure.

4. Contact Dermatitis: If there have been any new products used in the genital area, such as soaps, lotions, or condoms, contact dermatitis could be a possibility. This is an allergic reaction that can cause redness and irritation.

5. Folliculitis: This is an inflammation of the hair follicles, which can occur in the genital area and may present as red bumps. It can be caused by bacterial infections or irritation from shaving or friction.

Given that the symptoms are mild (not painful or severely itchy), it is still advisable to monitor the situation closely. Here are some recommendations:
- Maintain Hygiene: Ensure that the area is kept clean and dry. Gently wash with mild soap and water, and avoid using harsh soaps or products that could irritate the skin.

- Avoid Irritants: If any new products have been introduced, consider discontinuing their use to see if symptoms improve.

- Observe Symptoms: Keep an eye on the red spots and any changes in odor or discharge. If the symptoms worsen or do not improve within a few days, it is important to seek medical attention.

- Consult a Healthcare Provider: Since the symptoms began after a sexual encounter, it is prudent to consult a healthcare provider for a thorough examination and possibly testing for STIs. Early diagnosis and treatment are crucial for any infections.

In conclusion, while the symptoms may not seem severe, they warrant attention, especially considering the recent sexual activity. A healthcare professional can provide a proper diagnosis and treatment plan, ensuring that any underlying issues are addressed effectively.
