It's possible that the pain in the tip of your urethra during ejaculation could be due to a condition like prostatitis or urethritis rather than an infection. Prostatitis is inflammation of the prostate gland, which can cause discomfort during ejaculation. Urethritis is inflammation of the urethra and may also lead to similar symptoms.

Since you mentioned no pain when urinating, it might not be a typical urinary tract infection (UTI). However, I advise seeking medical evaluation from a healthcare provider for proper diagnosis and treatment recommendations. They can conduct tests if needed to determine the underlying cause and provide appropriate care tailored to your specific situation.

Always consult with healthcare professionals for personalized guidance on any concerning symptoms related to sexual health concerns like this one.
