Fetishism: Diaper fetishism -
Fetishists can wear diapers for sexual gratification. People with diaper fetishism have a desire to wear diapers even though it is not a physiological necessity, and may enjoy using their diaper to various degrees, depending on the person. Infantilists wear and use diapers in ageplay, although they are considered distinct from fetishists, as "diaper lovers" are sexually motivated to wear diapers, whereas "adult babies" wish to regress to the helpless state of a baby. Other sexual uses of diapers include omorashi, rubber or plastic fetishism. In BDSM roleplaying games, diapers can be used as a power exchange to emphasize loss of adulthood or control over bodily functions. Alternatively, they can also be liberating, as an infantilist is granted the desired freedom to be a baby.
