Querelle has one heck of a shore leave. There are a couple of murders, a drug deal, some sex, some drinking, and a little bromance. Jean Genet breaks all the stereotypes of male homosexuality with this novel; the man-on-man sex scenes focus on guys who don't even call themselves gay.
The fact that the main characters defy categorization is what makes them dangerous. Using Muñoz's notion of queerness, ask yourself this: how does Querelle's behavior challenge the idea that a man's sexuality is what makes him a man?
Genet's sailors are all living life "at great speed." If this sounds reckless and self-destructive to you, that's because it is. But what can Querelle tell us about the inherent harm caused by many men's (and women's) self-restrictive gender performances?
