In the song, the narrator is a teenage slut prone to giving her boyfriend blow jobs in movie theaters. Since the predicament of finding oneself sexually used, abused and discarded is largely a female problem, again, I'll defer to Naomi Wolf. Wolf advocates that young women, during the course of an initiation rite, make a pledge in front of older women never to use sex to get love, power or money. That makes good sense until marriage. Wolf's suggestion is only a slight variation on a few thousand years of collected wisdom.
Sex is as much spiritual mystery as physical fact.
The physical part of you is not some piece of property belonging to the spiritual part of you. God owns the whole parts. Morissette appears to have all the mental stability of a Tennessee Williams character. She is certainly high maintenance. If you were able to escape the John Wayne Bobbit incident, consider yourself lucky.
