What are common causes of irritation in the urethra?

Irritation in the urethra can happen for a few reasons. One major cause is infection. Sexually transmitted infections (STIs) such as gonorrhea, chlamydia, and even Mycoplasma genitalium are known to inflame the urethra. These infections can bring about symptoms like burning or discomfort during urination and sometimes discharge. Additionally, bacteria that cause urinary tract infections, like E. coli, can also irritate the urethra. Another group of causes relates to non-infectious factors. For instance, some chemicals found in soaps, bubble baths, or spermicides might irritate the sensitive tissues of the urethra. Physical trauma is another possible cause; injuries from activities like vigorous sexual actions, catheter use, or even tight clothing may contribute to irritation.
