In attempts to translate Foucault's arguments into a more direct postmodern discussion, I think he would support the concept of the collapse of social barriers by arguing that sexuality is not a natural category.

He seems to believe that sexuality is something that was created by our culture, our discourse, and that sexuality is basically a socially constructed category. In other words, there are no real categories of distinctions in life, but these categories originate from ourselves. They are man-made and not real.
