Oral fixations are considered to contribute to over-eating, being overly talkative, smoking addictions, overindulging in sugar, chewing on straws and toothpicks, and even alcoholism (known as “oral dependent” qualities). Other symptoms include a sarcastic or “biting” personality (known as “oral sadistic” qualities). Some literatures even suggest a link between oral fixation with oral sex where individuals fulfill their oral gratifications through phallic and ejaculant sensations. Another indicator is constant nail biting, putting fingers in the mouth as well as biting any future sexual partners they may have.
