A diaper fetish is when someone is sexually aroused or turned on by diapers. Diapers can be soft and comfortable and remind people of being a baby again, which can make them feel safe and relaxed. People with a diaper fetish may want to wear, use, or look at diapers, or they might want other people to wear diapers. People with a diaper fetish might also want to be treated like a baby, using the diaper as part of a role-playing experience.
