Hi, candaliesa. Welcome to poemranker.
It's clear that you've got the basics of writing poetry down. But I hope you're getting some ideas from these comments about the direction you should go with your writing. That is, away from overused rhymes and toward more specific and original images. A good rule of thumb is: If you've ever heard the rhyme or image you're thinking of using in any poem, song, or book, ever, DON'T USE IT. Don't be afraid to try for unusual connections between ideas or sounds. And don't be afraid to put the include the real details of your life in your poems. That's what hardworking poets have been doing for over a thousand years, and that's why we have so much good poetry.
Do your boyfriend's grooming habits remind you of a duck preening in a pond? Use that!
What is it that reminds you? The way he sniffs his underarms, like a duck rooting under a wing with his bill? Great!
What rhymes with "preening"? Meaning, intervening? Okay! How about "darjeeling"? It's close enough.
Did you ever walk around the city park pond with your boyfriend? Sure!
That's how easy (or how difficult) it is. Watch for images, things, people, you can relate to your life or ideas. Then use them. Try to make the rhymes work for the content. Try to make them distinguish your poem. Don't get discouraged.
Here's a good idea of rhymes that are overused, and how overused they are:

Good luck. Seriously, don't give up.
