Nature 
Sexual perversions depart from the normal in the following respects: disregard for the barriers between species (man and animals); insensitivity to barriers imposed by disgust (faeces, urine, etc); transgression of the incest barrier (prohibition of sexual gratification with close blood relatives); homosexuality; and transference of the part played by the sexual organs to other organs and different parts of the body. Deviant sexual behaviour patterns may involve or result in sexual violence and may cause marriage breakdown or impotence. They encourage prostitution and may lead to crime and can result in disease, injury, death and murder.
Incidence 
Sexual deviations include incest, male homosexuality, lesbianism, trans-sexualism, sadism, masochism, sodomy, bestiality, voyeurism, sexual exhibitionism, paedophilia, necrophilia and masturbation; they may be manifested in pornography or in obscenities and violence.
Counter-claim 
Sexual perversion depends on the what is meant by normalcy and leads to a wide variety of meanings. If normal sex is whatever minimal erotic activity required to promote conception with an appropriate partner, all else is irrelevant or immoral. If sex is for pleasure to consenting adults then perversion is inflicting pain in the short or long term. If sex is the expression of mutual love, perversions are expressions of hate or being manipulative. If sex is a way of communicating, deceit is a perversion. Masturbation, while not exactly perverse, it is not sexual as talking to yourself is not a whole conversation.
