Why does the urethral opening hurt after ejaculation, and what should I do?

Generally, the possible causes of pain at the urethral opening after ejaculation may include prolonged sexual activity, overly frequent sexual activity, prostatitis, urethritis, and seminal vesiculitis. If discomfort occurs, it is recommended to seek medical attention promptly and receive targeted treatment under a doctor's guidance. Detailed explanations are as follows:

1. Prolonged Sexual Activity

Prolonged sexual activity may cause the urethra to remain congested and subject to friction for extended periods, which could lead to minor injuries or inflammation of the urethral mucosa, resulting in pain at the urethral opening after ejaculation. It is important to maintain good sexual hygiene and keep the urethral opening clean. Additionally, control the duration of sexual activity to avoid excessive congestion and friction.

2. Overly Frequent Sexual Activity

Excessively frequent sexual activity may cause the urethra and genital organs to remain congested and fatigued for prolonged periods, thereby reducing the resistance of the urethral mucosa and making it more susceptible to inflammation or injury, which could lead to pain at the urethral opening after ejaculation. Maintain healthy lifestyle habits and avoid excessive fatigue.

3. Prostatitis

Prostatitis may be triggered by bacterial infection, unhealthy lifestyle habits, or unhygienic sexual practices. Prostatitis can cause damage to the prostate mucosa, and semen may irritate the damaged mucosa during ejaculation, potentially causing pain at the urethral opening after ejaculation. Symptoms such as frequent urination, urgency, painful urination, and discomfort in the perineal area may also occur. Treatment may include medications such as levofloxacin tablets, ciprofloxacin hydrochloride tablets, or amoxicillin tablets, as directed by a physician.

4. Urethritis

Urethritis is mostly caused by bacterial infection of the urethra. Bacterial infection leads to congestion, swelling, and damage of the urethral mucosa, and semen may irritate the damaged mucosa during ejaculation, causing pain at the urethral opening after ejaculation. Symptoms such as urethral itching, frequent urination, urgency, and painful urination may also be present. Under the guidance of a qualified physician, medications such as azithromycin granules, cefixime granules, or roxithromycin tablets may be used for treatment.

5. Seminal Vesiculitis

Seminal vesiculitis is usually caused by bacterial invasion, with inflammatory factors irritating the surrounding tissues of the seminal vesicles. The inflammation may cause congestion and edema of the seminal vesicles and surrounding tissues, and semen passing through the inflamed area during ejaculation may lead to pain at the urethral opening after ejaculation. Symptoms such as hematospermia (blood in semen) and painful ejaculation may also occur. Medications such as azithromycin tablets, ciprofloxacin hydrochloride tablets, or doxycycline hydrochloride tablets may be used under medical supervision to alleviate symptoms.

Maintain good lifestyle habits and personal hygiene in daily life. If any discomfort occurs, seek medical attention promptly and follow the doctor's instructions for treatment.
