Actually, you should find iambic pentameter to very closely mimic natural speech. I can tick off my friends pretty quickly by speaking in iambic pentameter. Once you've got the hang of it, it's pretty easy.
The most important rule that Shakespeare learned about this form of poetry is "learn when to break the rules." If you strictly adhere to the meter and apply syllables where they "sound good," you're going to miss a lot.
Step 1. Write out what you want to say.
Step 2. Write it again, with only ten syllables.
Step 3. Aim for the iamb, but don't be anal. Use metaphor/simile to make it fit better.
In the case of epic poetry like "Sir Gawain and the Green Knight," you'll also find a bob-and-wheel at the end of a stanza that makes the ending of that stanza obvious. Do a Google search on bob-and-wheel and you should be in good shape.

An epic not unlike the one you seek
Can flow from tongue to keyboard without pain.
Remember not to overdo it, though.
For ENWorlders are a fickle lot
to please.
Our faith in you is true:
The words shall come with ease.
A comedy from you
With eagerness we'll seize.
