allen ginsburg's poem about his sphincter comes to my mind ...
I hope my good old asshole holds out
60 years it's been mostly OK
Tho in Bolivia a fissure operation
survived the altiplano hospital--
a little blood, no polyps, occasionally
a small hemorrhoid
active, eager, receptive to phallus
coke bottle, candle, carrot
banana & fingers--
Now AIDS makes it shy, but still
eager to serve--
out with the dumps, in with the condom'd
orgasmic friend--
still rubbery muscular,
unashamed wide open for joy
But another 20 years who knows,
old folks got troubles everywhere--
necks, prostates, stomachs, joints--
Hope the old hole stays young
till death, relax.
