This Man and His Manhood

It needs to Grow Fast – Tall as a Crane,
To Stay as A Player – Remain in the Game.
Perform at a Task for Hours on End,
Never to Shrink – Never to Bend.

It also Might Jump to Immediate Call,
While raking the Leaves or Painting a Wall.
Sometimes swell Slow like a Slithering Eel,
While jointly Preparing the Days Evening Meal.

This Man and his Manhood have Certainly Aged,
And brought me Arthritis most Sadly Engaged.
It stiffens my Joints that Rarely are Bent,
Why can’t this Disease be Selectively Sent?
