It started as a joke.  I just couldn't resist the idea of singing a love song about refusing to sing love songs because of love-song phobia.  Then I fleshed it out with references to other phobias and superstitions, and in final form it's about the superstitions people add to romance.

My wife says this is my "Every Rose Has Its Thorn."

------------

I've always been afraid of love songs.
Like a camera to a tribesman,
I would rather turn down bribes than
steal the soul of this love.

So you'll just have to get used to the fact that
I'm never gonna sing the words 'I love you'
I'll have to find another way to tell you
and compel you to my arms
and though I know that rhymes with 'charms'
I won't
'cause I've always been afraid of love songs.

I tread with extra care near love songs.
I don't want to be the one to
make the terminal affront to
break the back of this love.

So you'll just have to get used to the fact that
I'm never gonna sing the words 'I love you'
I'll have to find another way to tell you
and impel you to my side
and though I know that rhymes with 'bride'
I won't
'cause I've always been afraid of love songs.

I've always been afraid of love songs.
Like a hammer to a mirror
If I shatter, trapped in fear or
loathing if I break this love

So you'll just have to get used to the fact that
I'm never gonna sing the words 'I love you'
I'll have to find another way to tell you
and propel you next to me
and though that rhymes with 'sexually'
I won't
'cause I've always been afraid of love songs.

I'm never gonna sing the words 'I love you'
'cause I've always been afraid of love songs.
