These are taken from a Rhyme Zone site where there's a competition for writing a romantic first line & an unromantic second line.  A few of the entries:

Love may be beautiful, love may be bliss
But I only slept with you, cause I was pissed

I love your smile, your face, your eyes
Damn, I'm good at telling lies

My darling, my lover, my beautiful wife:
Marrying you screwed up my life

My love you take my breath away
What have you stepped in to smell this way?

My feelings for you no words can tell
Except for maybe "Go to hell"

What inspired this amorous rhyme?
Two parts vodka, one part lime
