here are a few limericks on the subject of virgins that i've come across.

an innocent maid from penzance
decided to take just one chance
so she let herself go
in the lap of her beau
and now all her sisters are aunts

or

an innocent maiden from Maine
declared she'd a man on the brain
but you knew from the view
of the way her waist grew
that it was not on her brain she had lain

or

there was a young maiden called Flynn
who thought fornication a sin
but when she was tight
she thought it alright
so everyone filled her with gin

all the rest are far too rude to post here
