Frotteuristic Disorder involves:

Frotteuristic Disorder is characterized by the act of touching or rubbing against a non-consenting person, typically in a crowded situation, for the purpose of sexual arousal. This behavior is often performed without the victim's consent and is considered a paraphilic disorder due to the sexual nature of the actions involved. The focus is on the arousal that comes from engaging in this non-consensual interaction, highlighting the key aspect of the disorder, which is the lack of consent from the person being targeted.

The other options do not accurately reflect the characteristics of Frotteuristic Disorder. Fear of rejection in public settings pertains more to social anxiety, while compulsive thoughts about cleanliness and order relate to Obsessive-Compulsive Disorder. Seeking excessive validation from others aligns with issues of low self-esteem and may be indicative of dependent personality traits but is not connected to Frotteuristic Disorder. Understanding the definition and implications of Frotteuristic Disorder is essential for distinguishing it from other psychological conditions that might involve interpersonal interactions.
