Dr. Labia is conned by his editor into writing a weekly column about the hidden delights of anal sex. His secretary "accidentally" gives out his private phone number and address, and the "doctor" is bombarded by herds of horny ladies seeking first hand help. His biggest fans begin showing up at his front door, Persuading him to invade their "back-door". Dr. Labia gets so much action that he has to resort to employing other men to pretend that they are him. From beginning to end, Dr. Anal is guaranteed to elevate our blood pressure (among other things).
