From Psychology Today:
A paraphilia is a condition in which a person’s sexual arousal and gratification depend on fantasizing about and engaging in sexual behavior that is atypical and extreme. A paraphilia can revolve around a particular object (children, animals, underwear) or around a particular act (inflicting pain, exposing oneself). Most paraphilias are far more common in men than in women. The focus of a paraphilia is usually very specific and unchanging.
Thank you for that term. I’m going to have to commit it to memory and use it. How in the world did “butt” get taken off the list of examples?
