Frotteuristic Disorder involves which of the following behaviors?

Frotteuristic Disorder is characterized by sexual arousal that results from touching or rubbing against a non-consenting person, typically in a crowded setting, such as public transportation. The behavior is a concrete manifestation of the disorder, where the individual derives pleasure from making physical contact without the other person's consent. This aligns directly with the correct answer, emphasizing the sexually motivated actions aimed at non-consenting adults.

The other options involve issues that, while related to interpersonal relationships or anxiety, do not specifically describe the behaviors associated with Frotteuristic Disorder. Interpersonal conflicts in romantic relationships pertain more to relational dynamics rather than the specific arousal mechanism tied to this disorder. Fear of social intimacy relates to anxiety or avoidance in social situations, which does not reflect the sexual nature of Frotteuristic Disorder. Persistent anxiety about sexual performance addresses issues of self-esteem and anxiety in sexual settings, diverging from the non-consensual aspect that defines Frotteuristic Disorder. Thus, the distinct focus of the correct option on non-consenting sexual encounters accurately depicts the specific behaviors inherent to the disorder.
