Pain during ejaculation can be related to a variety of factors, including but not limited to sexually transmitted infections, prostatitis, and urethritis. This pain may be accompanied by symptoms such as frequent urination, urgency, painful urination, and increased urethral discharge, and sometimes the symptoms are more pronounced after sexual intercourse. If the pain is accompanied by hematospermia (blood in semen), this could be a sign of a more serious condition, such as prostate stones or tumors.

Another possibility is physical injury during ejaculation, such as overly vigorous sexual activity or masturbation, which can also cause pain during ejaculation. This pain usually occurs immediately after ejaculation and may persist for a period of time.

If symptoms continue to worsen and are accompanied by fever, hematuria, or hemospermia, it is necessary to consider whether there is a serious health problem, and you should seek medical attention immediately for a detailed examination.
