Can a very active sex life in the early years affect one’s sexual life later?

A very active sexual life in youth does not precipitate an early termination of the sex drive or capacity. On the contrary, persons having a strong sexual interest and capacity in the early years are more likely to retain the same in the later years. This was confirmed by a longitudinal study on sexual behavior and old age.

What are the most common conditions which could decrease sex drive in later years?

The common reasons for a reduced sex drive in later years are
  1. Monotony and loss of interest
  2. Changes in physical appearance
  3. Misconceptions about one’s waning sexuality
  4. Lack of communication
  5. Depression
