Shakespeare showed the way in terms of writing about desire with his sonnet #129.

The expense of spirit in a waste of shame
Is lust in action; and till action, lust
Is perjured, murderous, bloody, full of blame,
Savage, extreme, rude, cruel, not to trust,
Enjoy'd no sooner but despised straight,
Past reason hunted, and no sooner had
Past reason hated, as a swallow'd bait
On purpose laid to make the taker mad;
Mad in pursuit and in possession so;
Had, having, and in quest to have, extreme;
A bliss in proof, and proved, a very woe;
Before, a joy proposed; behind, a dream.
All this the world well knows; yet none knows well
To shun the heaven that leads men to this hell.
                  (from Shakespeare's Sonnets, #129)

      By adopting a third person perspective on his own experience, Shakespeare is able to express both the intensity of desire and the moral feelings that sometimes follow its indulgence. 

       The argument that lust leads to disgust might satisfy the moralist, but hardly matches the universal situation, where the reality of desire is that we often enjoy it without succumbing to disgust.

       The question arises whether we we push the poetic envelope somewhat further, by expressing the positive intensity of desire in the first person without lapsing into bad taste..

       A contemporary illustration comes from Sonnets 2000: :

                  13.
 

Anemones are delicate creatures
Whose slow quivering motions beckon us
To relish their mysterious features 
With a shy charm that is ingenuous. 
The inner architecture I can glimpse,
Initially indistinct and blurry:
Those corkscrew curls, those wisps of flesh called nymphs,
Veil hollow, contour, oval, and millefeuille.
I enter that baroque lobby, thrilling 
To oyster-like tissue, pearl of pure flesh,
Mauve and rose and limpid pink, distilling 
Wonder that generates the world afresh,
As I realize that I am seeing 
The immense pleasure field of your being.

 

                (from Stephen Denning's Sonnets 2000)
 

         Here the approach taken is one of analogy to nature, leading sinuously towards "the pleasure field of your being". 

         A more violent approach is adopted in Sonnet #14: 

 
                     14.

Breathless, I plunge headlong into those depths,
Driving deeper with each bestial stroke,
Yet also sensing ascent to a crest
On which celestial beings evoke
Sensations of velvet and ambrosia, 
The savor of which I have a foretaste.
Yet I know at the moment of closure 
All trace of this divine bliss is effaced:
At the instant when I am on the brink
Of sharing the gods’ prowess without bounds, 
A little flick will suffice, and I sink
Unmanned to my terrestrial surrounds.
Yet so sweet is this fore-glimpsed sensation,
I wait craving for the next frustration.
 

                (from Stephen Denning's Sonnets 2000)

        The poem goes on to explore the mysteries of the experience, leaving the author at the end "craving for the next frustration".
