Absolutely nothing wrong with sleeping between 8 and 9 hours, you're actually exactly in the healthy range.

I have the same profile : no caffeine or other stimulants, good volume of physical activity; I don't need any reminder to go to bed, I get the obvious the call by being quite tired.

Discussing sleep with people, I found two types that are dominants:

- people who heard "between 7 and 9 hours" and remember "8 hours" (can't say they're wrong here!) - people who heard "between 7 and 9 hours" and remember "the goal is 7 hours", and actually sleep between 5 and 7 hours
