Maybe because of some of the following?:

- it's embarrassing to talk about your sex life, and maybe especially gaps in it, online? - it's naturally private and people value their privacy, particularly online? - people are so taboo about it that they don't even want to record it for their future self? - it just gets lumped in with "sleep"? - it doesn't take up a significant enough amount of time?

All of these depend on the person, of course.

> it's naturally private and people value their privacy, particularly online?

People who value this type of privacy don't publish a decade of logs chronicling their daily life.
