THE NEW SWING SET

KILLING KITTENS

$240 for couples; $95 for single women. London and L.A.

With 40,000- plus members worldwide, this London-based swingers group relies heavily on its curated computer network. Champagne and oyster receptions, and candlelit romp rooms, make for an extra-sophisticated vibe, while the rule that all guests must wear Eyes Wide Shut– style masks keeps the sex as cold, detached, and British as possible. killingkittens.com

CLUB HERMIONE $150 for couples; $50 for single women. New England, Berlin, London

With parties that max out at just 20 heavily vetted couples and 10 single ladies, Club Hermione is the Ivy League of the underground sex party scene. Venues include fancy villas and yachts where guests mingle over cocktails before getting naked and humping all over expensive furniture. Gatsby would approve! clubhermione.com

MASS PLEASURES

$200 for couples; $30 for single women; $4,000 for VIP package. New York, L.A., Miami, Las Vegas, and London

Don’t expect plebeians at these monthly, bottle-serviced orgies hosted in ultraluxe venues, including— at least once—coco Chanel’s former Hollywood mansion. Those applying for membership must disclose details like their education level, occupation, and yearly income. masspleasures.com

SANCTUM CLUB

$250 for couples; $50 for single women. Beverly Hills

Got a hankering to watch a girl in a latex suit bathe herself in a tub of milk? This is the orgy for you! Applicants for these surreal yet formal black-tie events get an easy in if they can name-drop current club members. (This is Beverly Hills, after all.) To keep it paparazzi-proof, emphasis is placed on security and secrecy, and guests are urged to conceal their identities. sanctumclub.org
