"An interesting point lightly touched upon (haha) in the film is Pretorious' impotence, suggesting that his inability to get an erection is what led him into exploring other avenues of sensation, first S&M, and later the Resonator. With this in mind, the flexing stalk his pineal gland is on takes on a distinctly phallic interpretation, further linking horror and sexuality."
