Freud classified atypical sexual behaviors as distortion of original course (pervasion) that developed because of the effects of early interpersonal relationships on the abnormal mind.
Explanation:
Abnormal conduct is any behavior that detracts from the standard. Psychologists be using four common criteria to classify abnormal conduct: infringement of social norms, statistical rarity, physical distress, and disordered behaviour.
Deviance in sexual behaviour (pervasion) is a sort of human behavior which diverges from what is seen as orthodox or normal. This applies to a variety of ways of deviation, it is mostly used to explain sexual behaviors considered particularly irregular, repulsive or obsessed.
