Sexual variance.
Any sexual behaviour which is not accepted as usual in the society in which you live. Examples in Western society are sadism and voyeurism.
Any type of sexual practice which society regards as abnormal. Deviation may be related to the activity, such as exhibitionism or sadomasochistic sex; or to a perceived sexual object, for example, shoes or clothes (fetishism). Different cultures have different values, but the attitude to these matters should depend on whether the deviation is antisocial or harmful to the participant(s). For example, paedophilia is generally seen as harmful and requiring sanctions such as imprisonment, whereas many see simple fetishism as harmless.
Paraphilias refer to atypical patterns of sexual behavior, typically observed more frequently in men, where the ultimate goal of sexual intercourse is not the primary objective. Examples of sexual deviations include exhibitionism, fetishism, pedophilia, and transvestism.
