Perhaps my favorite song of the genre is called "CHASTITY BELT" which can be found at www-cs.canisius.edu/~salley/Bard.book/chastity.html 

among other places. To give you an idea, one of the verses goes:

Alas, gentle errant, I am no maiden
I'm married to Sir Oswald the cunning old celt,
He's gone to the wars for a twelve-month or longer
And taken the key to my chastity belt.

Good luck.
