Relief from stress - Relief from stress is often given by AB/DLs as an explanation for their desires. Acting on these desires can be quite relaxing in the short term. However, given how difficult and troubling these desires can be, relief from stress might be as much a justification as an explanation. For example, the AB/DL might be in the superficially carefree position of having a 'mommy' or 'daddy' looking after their every need, such as diaper changes, feeding, and bathing. However, the AB/DL will need to overcome the difficulty of establishing the relationship, and be careful to keep the relationship from being short-lived due to imbalance.
Adult Babies and Diaper Girls
BDSM - Diapers are sometimes used during prolonged bondage sessions, not only as a method to control and shame the submissive partner, but also to allow longer periods of bondage. In Total Power Exchange, diapers are sometimes utilized for the dependency they represent of the wearer on their master to be checked and changed.
