Because

Oh, because you never tried
To bow my will or break my pride,
And nothing of the cave-man made
You want to keep me half afraid,
Nor ever with a conquering air
You thought to draw me unaware --
Take me, for I love you more
Than I ever loved before.

And since the body's maidenhood
Alone were neither rare nor good
Unless with it I gave to you
A spirit still untrammeled, too,
Take my dreams and take my mind
That were masterless as wind;
And "Master!" I shall say to you
Since you never asked me to.
