Painful urethral stinging after urination suggests a urinary tract infection (UTI), which may be related to inadequate personal hygiene in daily life. It may also result from compromised immune function. Local infection triggers inflammation, which can easily damage the urinary mucosa; urine passing over these damaged areas causes pain.
