What sin, a name?

Being stuck with the handle "Percival" has had its downsides.
The one upside, in my youth, was not being the target of the annual limerick competition.
However Trev Tonkin -- whom I have always suspected to be a closet heterosexual and who was, accordingly, I suspect again, somewhat jealous (indeed as he was of his brother Steve [Bonkin'] Tonkin) -- penned the following to win the 19** competition and to eulogise my (then) youthful contributions to geriatric well-being:

An old hag from Moribundup
Had a **** that was shrivelled and bunged up
'Til a young man named Percy
In a sheer act of mercy
Shagged her from nightfall to sunup

The point of this remembrance?
The youth of today ... {sigh} ... what have they become?
Why are there no similarly charitable 16 year-old girls these days?
Were there ever?
