The High Priestess, acting for Inanna, is speaking to Dumuzi the new king.
My vulva, the horn,
The boat of Heaven,
Is full of eagerness like the young moon.
My untilled land lies fallow.
As for me, Inanna,
Who will plow my vulva?
Who will plow my high field?
Who will plow my wet ground?
As for me, the young woman,
Who will plow my vulva?
Who will station the ox there?
Who will plow my vulva?
The symbolism is, I hope, obvious to you. If you've ever looked at an anatomical picture of the female reproductive system, you may have noticed that the vagina is shaped like a horn, it curves upward and narrows towards the back.
On the male side, an old time plow (not the modern day tractor type) had a long, hard projection that pushed into the ground.
Dumuzi, the king replies:
Great Lady, the king will plow your vulva,
I, Dumuzi the King, will plow your vulva Inanna accepts him saying:
Then plow my vulva, man of my heart
Plow my vulva.
Then follows more details of the happenings
My eager impetuous caresser of the navel,
My caresser of the soft thighs;
He is the one my womb loves best,
My high priest is ready for the holy loins.
My lord Dumuzi is ready for the holy loins.
The plants and herbs in his field are ripe.
O Dumuzi, Your fullness is my delight.
The high priestess then directs things to be readied
Inanna called for the bed.
Let the bed that rejoices the heart be prepared
Let the bed that sweetens the loins be prepared
Let the bed of kingship be prepared!
Let the bed of queenship be prepared!
Let the royal bed be prepared!
This bed was set up in front of the entire congregation. The people watched the entire ritual including the sexual part.
He shaped my loins with his fair hands,
The shepherd Dumuzi filled my lap with cream and milk.
He stroked my pubic hair.
He watered my womb.
He laid his hands on my holy vulva,
He smoothed my black boat with cream,
He quickened my narrow boat with milk.
He caressed me on the bed.
The King went with lifted head to the holy loins.
He went with lifted head to the loins of Inanna
He went to the queen with lifted head.
He opened wide his arms to the holy priestess of heaven.
We rejoiced together.
He took his pleasure of me.
He laid me down on the fragrant honey-bed
My sweet love, lying by my heart,
Tongue-playing, one by one,
My fair Dumuzi did so fifty times.
Now, my sweet love is sated.
