Diaper fetishism
Diaper fetishism, nappy fetishism or diaperism, is a sexual fetish in which a person feels a desire to wear or use diapers. This may or may not be accompanied by a medical need, but must be a desire.
Diaper fetishism is sometimes falsely conflated with pedophilia. The wearer derives pleasure only from the diaper and/or use of it. Being forced to wear diapers as a form of humiliation is sometimes a behavior encountered in sexual masochism.
As of 2013, little analysis of this paraphilia has been reported in medical literature.
Diapers in paraphilias
Those with diaper-related paraphilias differ widely in their focus of attention. There is no singular or archetypical behavior; therefore, a wide range of thought patterns and behaviors exist, but all tends to be a harmless and efficacious release from some kind of pressure.
While wearing diapers, a diaper fetishist generally experiences a comforting feeling. For other diaper fetishists, simply wearing a diaper, the bulky feeling and crinkly noise associated with it, is enough to cause the fetishist a form of erotic pleasure or sexual arousal.
