I usually use a tee on par 3's. Certain shots like an easy knock down 9-iron or any sort of wedge I won't use one, but those types of shots on par 3's are few and far between where I play.

It is the only place on the golf course that you can use a tee, you might as well take advantage of it. Even if it is just to get the ball 1mm above the ground.

It is not required and I have known several good golfers who never used them. And if you don't want to use one, that is fine too. No course will frown upon someone not using a tee.
