Destroyers, or "Shit Eaters," are the UNSC's main sex machines. Many Marines go to destroyers to have sex with Cortana. So far, Cortana is known to have sex with over 10,000 Marines, including Master Chief, where they've had sex almost 100 times. Many Elites and Grunts go to Destroyers just to have sex with each other. Many Marines even masturbate with Cortana. Everyone who has sex with Cortana dies, except Master Chief.
