What are the reasons for difficulty in achieving ejaculation during sexual activity and how to find answered questions

Patient's question:

Patient Age: 66
Detailed Condition and Purpose of Consultation: Difficulty achieving ejaculation during sexual activity

Doctor's answer:

As men age, the secretion of semen decreases, and they may not always achieve ejaculation during sexual intercourse. This is entirely a normal physiological phenomenon or a manifestation of the aging process. For instance, if the hardness of erection diminishes during sexual activity to the extent that it fails to stimulate ejaculation, there is no need to force ejaculation. However, if ejaculation occurs, it should not be intentionally avoided.
