Sexual fetishes are a product of "Id", a dark, inaccessible part of our personality; a celestial body overflowing with the unstable energy derived from humanity's infinite excitation.
"Id", an immovable force of pure instinct seeking to satisfy instinctual needs, ignorant to reality, ignorant to organization, ignorant to collective will, and fueled by the pleasure principle.
It is of the "Id" that we project the disgusting details of our sexual desires, that we share with a select few, that others of us are unable to express.
