O Fantasma

What no one seems to find in the film is the gradual regression of the hero to a canine level. We begin with his attachment to his dog as the only keen affection in his life -- they kiss, fondle, etc. Like the dog, Sergio tends to judge and eventually express his erotic energy through smell (e.g. the scene where he licks the shower wall), and at the end he is wandering the heaps of refuse poking and smelling at random, as the dog does.

His sexual hunger is probably to be passively possessed, but his culture and friends may demand a more active role. Yet he never finds satisfaction in such a role -- he rebuffs the fellow who's going down on him in the toilet -- and one imagines that what he really wants from the hunky motorcycle driver is to be assaulted and possessed by him. His loneliness and social anomie, as well as his undefined erotic drives, send him down a spiral of dehumanizing impulses until he seems to have forsaken any recognizably human responses.

It's an interesting and original film fantasy (I agree with the comment that "eye candy", perhaps the editor's addition,indicates a pornographic intent) but too simply developed to challenge your imagination.
