Pus

Pus, in some ways, might be advantageous…
For fellas who feel courageous…
It’s slippery goo,
That, like, helps with the screw, 
Hoping meantime it isn’t cuntagious!

Pussy (adj)

Other people’s small parts may drip pus,
With all sorts of concomitant fuss:
It’s a nuisance, of course,
Which provokes great remorse
In those poor folk concerned, (never us!)

Touch

A young fellow who does what he pleases
Treats lightly the social diseases:
He doesn’t mind much
About physical touch
But he handles girls’ panties with tweezers.

Risk averse

Mister Cohen was always meticulous,
Almost, one might say, ridiculous:
Shy of disease,
He was never at ease
Till he took down the lady’s particulars.
