The 17 the song is referencing is the 17 ways Morris is seducing the woman he's with. This composition by Prince was originally titled "Proposition 17" in it's early stages (although it is said that the song is the original but re-titled).
Some of the lines/lyrics from this song was used in the movie Purple Rain. In earlier scripts (when the movie was called Dreams), almost every line in this song was used.
