Tetsuo: The Iron Man is about a man deeply insecure about his sexuality. In his nightmare his girlfriend terrorizes and ultimately rapes him with her evil snake penis. When he awakens they have sex, and he is fully in control. During the penis drill sequence his is overcome with rage and lust, but in the end the Girlfriend defeats him. She straddles him: now she is in control of the sexual situation. Later, he finds himself fighting with, and ultimately united with the Metal Fetishist as they romantically float in the nude in their shared cocoon. At the conclusion the Salary Man is one with his new male partner, and he is the bottom portion. As he moans out words he drools semen-like fluid. He has literally become a penis; he has become comfortable with his sexuality.
That's my quick and dirty interpretation. The film indulges in its action sequences and its plot twist, and the sex stuff is obviously tongue-in-cheek: the penis drill is in equal parts a poetic symbol and a hilarious gag.
Most of the sequences could be cut by a couple of minutes and the film would be better for it. Overall I recommend the film. Sometimes I wonder what Lynch or Cronenberg film would be like if all the "normal" stuff was removed. This is what you'd get! 67 minutes of fury, sex, and furious sex.
