Is it normal for a 90-year-old person to have sexual needs?

Patient's question:

Is there a problem? Physiological? Psychological?

Doctor's answer:

Hello: Most men can continue their sexual activity until they are over 70 years old. Some of them can maintain it until around 80 years old, and a few still have sexual desires even at the age of 90. Physiological functions do not decline with age; what gradually declines is reproductive function.
