In response to Wy's post, it's not all that uncommon for one gender to write songs for the opposite one. A case in point was the Forester Sister's hit from the 1980's "Talkin' 'bout Men" which was actually written by two men. And John Prine's "Angel from Montgomery" which was about an old woman.

As for your lyric, can't think of add on verse at this time, but may take a look at it later.

Peace,
Brian

Wait a minute! I think I've come up with at least the first line. How about this?

So I'll just jump in the water
And swim on toward the shore
And remain active and on the move
Till I find one I'll adore
And if I have to swim several miles
It'll be worth it when I see her smile
