Empty Wineglass

It seems irrelevant to me
I ignore the thing itself
When there is no wine to see
Then I leave it on the shelf

Unfulfilling when unfilled
It does not ignite desire
But when with wine instilled
Then it can light my fire

Ah! What caresses then
And kisses in the night
But still just looking through
When held up to the light

And what of you my dear
Is it you I truly see
Or is what draws me near
What you might gratify in me?

And when do I embrace you
Unconscious of your uses
And will I always hold you
Longing only for your juices?
