Itchy Sensations Below the Penis: Causes and Solutions

Itching in the urethra beneath the penis?

Hello Doctor: A week ago on Sunday, I had sexual intercourse, and everything felt normal the next day.
That evening, I used a vibrating massager typically used in adult videos, placing it under the base of my penis and on the frenulum until I experienced a tingling sensation and ejaculation.
However, starting the next day, I began to feel itching in the urethra beneath my penis, although there was no pain.
Massaging the area near the base close to the scrotum felt particularly pleasant (similar to the sensation of being bitten by a mosquito, where you feel itchy and want to scratch).
I also experienced some burning and slight itching while urinating, but again, no pain.
On Monday morning, I visited a urologist, who performed a urinalysis, and the results came back normal.
The doctor prescribed anti-inflammatory medication for me to take home.

I have experienced similar symptoms twice before, and during those visits to the clinic, high bacterial counts were found in my urine, leading to antibiotic treatment.
Why is it that this time, with similar symptoms, my urinalysis results were normal? Currently, I have noticed some itching in the perineal area (the area between the anus and the scrotum; I am unsure of its specific name), and I feel the urge to insert my finger into my anus to massage that itchy area.
Should I seek a consultation at another hospital for further examination? Could this be prostatitis or some other prostate-related condition? I am nearing the end of my anti-inflammatory medication, and while my symptoms have improved somewhat, they have not completely resolved.
Additionally, I have noticed that this week, it has been difficult to maintain an erection, and I am not getting erections as easily as before.
I also experience very mild pain in my left kidney, but it is not constant; it occurs suddenly.
Doctor, which specialty should I consult? What potential causes should I investigate?

It may be chronic urethritis caused by atypical bacteria, and further consultation and examination for treatment may be necessary.

More Info

Itchy sensations below the penis, particularly in the area near the urethra and the scrotum, can be caused by a variety of factors, including infections, irritations, or underlying medical conditions. Based on your description, it seems that you have experienced these symptoms after engaging in sexual activity and using a vibrating device for stimulation. Here’s a comprehensive overview of potential causes and recommendations for further evaluation.

Possible Causes
1. Irritation or Allergic Reaction: The use of a vibrating device, especially if it is not made of body-safe materials or if it has been used with lubricants or lotions that may cause irritation, could lead to localized itching and discomfort. Allergic reactions to materials or substances can manifest as itching without pain.

2. Infection: Although your urine test came back normal, it is still possible to have a localized infection that may not be detected through a standard urinalysis. Conditions such as urethritis (inflammation of the urethra) or balanitis (inflammation of the glans penis) can cause itching and discomfort. Sexually transmitted infections (STIs) should also be considered, especially if there are any additional symptoms like discharge or unusual odor.

3. Prostatitis: Given your symptoms of discomfort in the perineal area (the area between the anus and the scrotum), it is possible that you may be experiencing prostatitis, which is inflammation of the prostate gland. This condition can cause discomfort, itching, and urinary symptoms, including burning sensations.

4. Skin Conditions: Conditions such as eczema or psoriasis can also affect the genital area, leading to itching and irritation. These conditions may not always be associated with infections and can be exacerbated by friction or irritation.

5. Nerve Sensitivity: The sensation of itching and the urge to scratch may also be related to nerve sensitivity or irritation in the area, particularly after stimulation.

Recommendations for Further Evaluation
Given that your symptoms have persisted despite taking anti-inflammatory medication and that you have a history of similar issues, it would be prudent to seek further evaluation. Here are some steps you can take:
1. Consult a Urologist: Since your symptoms involve the genital area and urinary tract, a urologist would be the most appropriate specialist to consult. They can perform a thorough examination and may recommend additional tests, such as a culture of any discharge or further imaging studies if necessary.

2. Consider STI Testing: If you have not already done so, it may be beneficial to undergo testing for sexually transmitted infections, even if your symptoms do not strongly suggest an STI. Some infections can be asymptomatic or present with mild symptoms.

3. Evaluate for Prostatitis: If prostatitis is suspected, your urologist may perform a digital rectal exam (DRE) to assess the prostate and may recommend further tests, such as a prostate-specific antigen (PSA) test or imaging studies.

4. Review Medication and Allergens: Consider any new products or medications you may have used recently that could contribute to irritation. Discuss these with your doctor to rule out allergic reactions.

5. Monitor Symptoms: Keep track of your symptoms, including any changes in urinary habits, pain levels, or the presence of discharge. This information can be valuable for your healthcare provider in determining the underlying cause.

Conclusion
In summary, while your initial evaluation did not reveal any significant abnormalities, the persistence of your symptoms warrants further investigation. Consulting a urologist is a crucial next step to explore potential causes such as infections, prostatitis, or other dermatological conditions. Early diagnosis and treatment can help alleviate your symptoms and address any underlying issues effectively.
