Red and White Spots on the Corona: Urology Insights - Urology

Coronal sulcus red and white spots


Hello doctor, I recently had a sexual encounter where I received oral sex for about 30 seconds.
After that, lubrication was applied, and manual stimulation was performed, which caused some pain.
When I got home, I noticed red spots in the pubic area, each with small white dots on them.
Pulling back the foreskin causes pain.
Could you please tell me what the likelihood is that I have an infection or disease?

Is it possible to get it this way? I can only say that the probability is very low.
There is no answer that can guarantee a result, nor can it alleviate your anxiety.
If you have concerns and have engaged in risky behavior, it is advisable to see a urologist for examination and follow-up, especially since your condition may already be inflamed.
You should definitely consult a urologist.

When it comes to the appearance of red and white spots on the corona of the penis, it is essential to consider several factors, including the recent sexual activity you described. The symptoms you are experiencing could be indicative of a few different conditions, and while I cannot provide a definitive diagnosis without a physical examination, I can offer some insights based on common urological issues.

Firstly, the red spots you are observing could be a sign of irritation or inflammation, which may result from friction during sexual activity, especially if there was a lack of adequate lubrication or if the activity was vigorous. The presence of white spots could suggest a few possibilities, including the formation of small cysts, pearly penile papules (which are normal anatomical variations), or even signs of a sexually transmitted infection (STI).

Given that you mentioned experiencing pain when pulling back the foreskin, this could indicate a condition known as balanitis, which is an inflammation of the glans (the head of the penis) and can be caused by various factors, including infections (bacterial or fungal), irritants (such as soaps or lubricants), or even allergies. Balanitis can present with redness, swelling, and discomfort, and it may also lead to the formation of spots or lesions.

Another concern is the possibility of a sexually transmitted infection (STI), especially if there was any unprotected sexual contact. STIs such as herpes, gonorrhea, or chlamydia can present with various symptoms, including sores, redness, and discomfort in the genital area. If the red and white spots are accompanied by other symptoms such as discharge, fever, or systemic symptoms, it would be crucial to seek medical attention promptly.

It is also worth noting that if you have a history of recurrent infections or if you are uncircumcised, you may be at a higher risk for conditions like balanitis or other infections due to the accumulation of smegma or irritants under the foreskin.

In terms of the likelihood of having a disease, it is difficult to assess without a thorough examination and possibly laboratory tests. However, if you are experiencing pain, discomfort, or any other concerning symptoms, it is advisable to consult a healthcare professional, preferably a urologist. They can perform a physical examination, take a detailed history, and possibly conduct tests to determine the underlying cause of your symptoms.

In the meantime, here are some general recommendations:
1. Maintain Hygiene: Ensure that the genital area is kept clean and dry. Gently wash with mild soap and water, and avoid harsh soaps or irritants.

2. Avoid Irritants: If you suspect that a lubricant or other product may have caused irritation, discontinue its use.

3. Monitor Symptoms: Keep an eye on the spots and any changes in symptoms. If they worsen or if new symptoms develop, seek medical attention.

4. Consider STI Testing: If there is any concern about STIs, it is prudent to get tested, especially if you have had unprotected sexual encounters.

In conclusion, while the symptoms you describe could be due to irritation or a benign condition, they could also indicate an infection or other medical issue. Seeking medical advice is the best course of action to ensure proper diagnosis and treatment.
