Britney Spears' latest contribution to pop music's math textbook, "3," is a celebration of bedroom-floor activities involving more than two people, and I don't mean vacuuming! Though that might happen too, actually. But Britney coos naughty stuff about "Not only you and me/ Got 180 degrees/ And I'm caught between" and "Peter Paul and Mary gettin' down." (Where's Puff the Magic Dragon when you need him?) But believe it or not, Ms. Spears is not the first pop star to deal with said multipartner practice, and others have documented entirely different lovemaking activities at least as nontraditional. Herewith, an inventory of sex-obsessed songs that opt for flavors other than vanilla.

Awesome list, Chuck-- except "Orgasmatron" is, if I'm not mistaken, from Woody Allen's "Sleeper", not "Barbarella" (although "Barbarella" has *an* orgasmatron, I feel like it was called something else...)
I guess Frank Zappa is not mentioned as listing his songs with sexual "fantasies" would take too many pages.
