If you consider an object as something to be acted upon, of the 4 ways of representation you cited, only the first usually applies. Other ways of representation, in the examples I can think of, are often of active characters, either the corporate alpha male, or the frat-house bro. Sure, these are simplifications and stereotypes of men, but I don't think they can compare to the objectification of women through their sexuality, as portrayed through our mass media. Men act, women are acted upon.
