At an airline I used to work at, we had 2 tail strikes. All by Captains. One other occasion saw myself calling attitude twice followed by nudging the column discreetly forward due to LDG ATT 6 degrees and an unsafe landing technique being used (By the Captain)

Being in the left hand seat has taught me a whole lot about how to treat people, I think it's about time you let your defense mechanism down and let the little dude in! You're there as a coach as well as a Signature...
