Might be useful if the 'rhythm method' is your chosen type of birth of control.

I got rhythm
Period-tracking,
Won't get pregnant:
Who could ask for anything more?

No charge for this service. You're welcome.

LOL! Here's the debate counter-argument:

Life has just begun
Jack has found his Jill;
Don't know what you've done
But I'm all a-thrill

You've made my life so glamorous
You can't blame me for feeling amorous
Oh, 'S wonderful! 'S marvelous!
That you should care for me!
