Final answer:
Fetishistic disorder is an erotic fixation on nonsexual objects or body parts. It differs from sexual preference, as it may cause distress or impairment in functioning. The condition is complex and is part of the broad spectrum of human sexual behaviors. The answer is option C.
Step-by-step explanation:
Fetishistic disorder is an erotic fixation on nonsexual objects or body parts. This is a type of sexual disorder that entails a recurring and intense sexually arousing urge or behavior involving inanimate objects or body parts not typically seen as sexual in nature. For instance, someone with a fetishistic disorder may derive sexual pleasure from objects like shoes or articles of clothing, or body parts such as feet.
Psychosexual development, as theorized by Freud, indicates that unresolved conflicts in any of the sexual development stages may lead to such fixations. However, it is important to acknowledge the difference between sexual preference and fetishistic disorders, which can cause significant impairment in daily functioning or distress. It is a nuanced aspect of sexuality that varies greatly among individuals.
