"Sex Object" (Germany: "Sex Objekt") is a song by Kraftwerk from the album Electric Café (since re-released as Techno-Pop).
The song begins with the echoing words "Yes, no, yes, no" (Germany: "Ja, nein, ja, nein") before the melody comes in and spoken lyrics. The "Yes, no" motif returns throughout the song.
Throughout the song, worlds in various languages express timidity ("No! Yes! Why?") before progressing to acceptance ("Maybe, perhaps, now!, yes!").
