Paraphilia, sexual deviation (in Greek para παρά = besides and '-philia' φιλία = love) - in psychology and sexology, is a term that describes a family of philias that reference sexual arousal in response to sexual objects or situations which may interfere with the capacity for reciprocal affectionate sexual activity. ^{[citation needed]} Paraphilia is also used to imply non-mainstream sexual practices without necessarily implying dysfunction or deviance. Also, it may describe sexual feelings toward otherwise non-sexual objects. An individual who expresses paraphilia may be known as a paraphile.
