I can be stolen without being taken, shared without being given, and lost in seconds without ever leaving. What am I?

You can't live without me, although some make due. You can find me in a storm and you can find me in a drain. I'm meant to be wet but not from the rain.

If TWO is enough And THREE is a crowd, then what is FOUR and FIVE?

I have teeth but never bite, the first thing you grab when you turn off the light. I’m made of metal and need a twist, When I get lost I’m the one you most missed.

I once hugged the heart of a fragrant bloom, softly I drift on the gentle plume. I fall to the ground when my time is done, bright and kissed by the golden sun.
