Lee,
Sorry, know you're looking for help from Nelson... but you ended up with bmom who happens to have editing experience read your post. So I'm butting in.
It is all in your grammar. Just change the subjects from "I" to "we" and then make the verbs agree. You will have to refer to yourself in the third person, though. Look, here's your paragraph rewritten: (Don't know your dh's name so I will use "John"):
We have been together for nine years total and happily married for six. We met through work. Lee was a teller at John's bank. It took John over a year to ask Lee out, but on the very first date, Lee knew he was "the one." We were married October 24, 1998 and started trying to have children right away. However, we soon found out Lee could produce eggs capable of becoming babies. It was a painful time... but then a wonderful friend offered to donate her eggs to us. Thanks to her, in September of 2002 our son Flynn was born.

Simple as that....
If you think it sounds kinda awkward (and I would agree-- switching back and forth from first person to third is never ideal), there is another option (my personal preference): FORCE YOUR HUBBY to write part of the profile. That way you can use "I" in your part and he can use "I" in his part. This sounds more personal, anyway.
If your dh is absolutely refusing to write, you can fake it... ask him what his thoughts are, what he'd like to say in the letter.... take notes on what he says... and then write it for him--using as many of his own phrases as you can, so his own tone comes through--using "I" (just as if hubby was writing it).
Example:
Hello! We are Lee and John.We'd like to tell you about ourselves.....
John is the light of my life. We met when I was a teller at John's bank... I knew he was "the one" on our first date... (etc.)
(later)
My relationship with Lee is my greatest source of happiness. She is truly an amazing person: honest, loyal.... (etc.)
(later--unified voice again)
We live in a big home in the country. We have four dogs, two birds, an elephant, (etc).

If you do this approach, you will just have to play around w/ transitions between the "we" parts and the part where you write, and the part where your dh writes. In my humble opinion, if it's written clearly enough, the transitions could be as simple as a row of dashes _____________ separating the parts, to signal that a new "voice" is writing.
K, probably WAAAAY more than you wanted, so I'll quit rambling. Hope this helped a little.....
Good luck!
