Male tumescence is an assertion of the separateness of objects. An erection is architectural, sky-pointing. Female tumescence, through blood or water, is slow, gravitational, amorphous. In the war for human identity, male tumescence is an instrument, female tumescence an obstruction. The fatty female body is a sponge. At peak menstrual and natal moments, it is locked passively in place, suffering wave after wave of Dionysian power.
