Jean has a good answer. Even if the writing you produce lacks aesthetic merit and would be considered utter crap in comparison to quality literature, there are greater things out there than can be said with words, and expression more genuine than can be spoken through a love poem.
At the same, time what sort of poem do you need? What would you like it to say? From what time period and in what structure? What kind fo love (as separated by cultural understanding and layers of metaphysical significance)?
Narrow it down and I'll help you find something.
Cheers !
PS
weirdichi, both of those guys wrote some excellent poems. For example:
John Keats, Bright Star, Would I Were Steadfast as Thou Art
Bright star, would I were steadfast as thou art?
Not in lone splendour hung aloft the night,
And watching, with eternal lids apart,
Like nature's patient sleepless eremite,
The moving waters at their priestlike task
Of pure ablution round earth's human shores,
Or gazing on the new soft-fallen mask
Of snow upon the mountains and the moors;
No?yet still steadfast, still unchangeable,
Pillow'd upon my fair love's ripening breast,
To feel for ever its soft fall and swell,
Awake for ever in a sweet unrest,
Still, still to hear her tender-taken breath,
And so live ever?or else swoon to death.
W. B. Yeats, He Wishes for the Cloths of Heaven
Had I the heavens' embroidered cloths,
Enwrought with golden and silver light,
The blue and the dim and the dark cloths
Of night and light and the half-light,
I would spread the cloths under your feet:
But I, being poor, have only my dreams;
I have spread my dreams under your feet;
Tread softly because you tread on my dreams.
I like this one, as an examination of one facet of the words:
Alfred Austin, Love's Trinity
Soul, heart, and body, we thus singly name,
Are not in love divisible and distinct,
But each with each inseparably link'd.
One is not honour, and the other shame,
But burn as closely fused as fuel, heat, and flame.
They do not love who give the body and keep
The heart ungiven; nor they who yield the soul,
And guard the body. Love doth give the whole;
Its range being high as heaven, as ocean deep,
Wide as the realms of air or planet's curving sweep.
