Condom

"The Condum being the best, if not the only Preservative our Libertines have found out at present... yet, by reason of its blunting the Sensation, I have heard some of them acknowledge, that they had often chose to risque a Clap, rather than engage cum Hastis sic clypeatis [with spears thus sheathed]."

"Armour against enjoyment, and a spider web against danger."
