What is the meaning of the song whistle?

Answer 1

It's a song about oral sex, but the songwriter didn't want to just come out and say that, or the song would have been banned from radio airplay. It has long been a custom in Pop Music to use euphemism and innuendo when writing lyrics that might otherwise be controversial. Euphemism is a clever way of substituting another word for the bad word-- "the F-bomb" is a euphemism, and everybody knows what word you really wanted to say. In "Whistle," the singer uses innuendo, which means hinting about something without really coming out and saying it. He seems like he is talking about showing his girlfriend how to whistle (and in fact, he does whistle a few notes), but he is also talking about showing her how to put her lips on something else and blow it... in other words, his penis.
