Key to My Heart

This is an entry for the fun challenge at at beginner level - 'Activate My Heart' is the theme.

I am whole, I am complete,
One head, two arms, two legs, two feet.
I have spirit and I have a soul -
I have everything to make me whole.
I have something else: the key to my heart -
My most vulnerable and tender part.
Not everyone can use the key,
It opens a sensitive part of me.
Not everyone wants the key -
And that is simply fine by me!
