Why does my lower abdomen feel distended and painful after an erection for a long time?

In this case, the pain caused by holding back semen is not considered prostatitis. Generally, it will get better after rest or ejaculation. The key point is to pay attention to daily conditioning. Drink more water, urinate frequently, pay attention to rest, exercise appropriately, avoid catching cold, do not sit for a long time, do not ride a bicycle, do not hold in urine, avoid excessive sexual life and masturbation, eat less spicy food, less smoking and drinking, etc.

Common causes of testicular pain include: acute testicular epididymitis, prostatitis, hydrocele, fungal infection, testicular cyst, varicocele and other diseases. Common clinical symptoms of prostatitis patients include: frequent urination, urgency, and difficulty urinating. White secretions can be seen adhering to the urethral opening in the morning. Urinating may be accompanied by pain and discomfort in the perineum, lower abdomen, testicles, and lumbosacral region, which can have an impact on sexual function and fertility. Due to the differences in causes, it is recommended that you actively go to the hospital for a comprehensive examination and treatment after the diagnosis is clear.

If the erection lasts for more than 30 minutes without ejaculation, or if you hold back semen and have frequent erections, long-term prostate congestion will cause poor local blood circulation, leading to testicular swelling and pain, dull perineal pain and other conditions. You have to control yourself, don't stay erect for a long time, don't hold back your semen frequently, and it will usually get better on its own.

In this case, it is recommended to avoid overexertion, live a regular life, refrain from smoking and drinking, and avoid spicy food to avoid aggravating the condition.
