What might cause an itchy urethral opening?

There are a few things that can make the urethral opening feel itchy. One reason can be irritation from soaps, lotions, or other chemicals that come in contact with the skin. In some cases, an allergic reaction to these substances can make the area feel itchy and red. Sexually transmitted infections, like gonorrhea or chlamydia, can also cause irritation and discomfort, sometimes with discharge, and are discussed in the WHO guidelines for managing urethral discharge syndrome. Another possibility is local inflammation, like balanoposthitis, which affects the tip of the penis and can extend to the nearby urethral opening. In a rare case, conditions like juvenile allergic urethritis have been seen, where an allergic reaction may lead to urethral irritation. Overall, the itchiness is often due to a mix of irritation or allergic responses and possible infections.
