Why might there be discomfort in the urethra after ejaculation?

There are several reasons you might feel discomfort in your urethra after ejaculating. One common cause is urethritis, which means the tube that carries urine and semen is inflamed, usually because of an infection or irritation. This inflammation can cause pain during and after ejaculation. Another possibility is retrograde ejaculation, where some of the semen goes backward into the bladder instead of out through the tip of the penis, leading to pain as the body reacts to this unusual flow. Additionally, a narrowing of the urethra, known as a urethral stricture, can cause discomfort because the passage for semen is tighter than normal. Sometimes, bleeding in the semen (hematosepermia) can also cause pain and discomfort if there is irritation. These ideas come from research that looks at how the health of the urethra can affect ejaculation and why pain might occur afterward. If someone experiences this discomfort frequently, it is a sign to speak with a doctor for proper evaluation and care.
