Diaper fetishism
Diaper fetishism (American English), or nappy fetishism (British English), is a type of garment fetish in which a person derives pleasure from themselves or partners wearing or using a diaper. Diaper fetishism can be performed on its own or incorporated into other various kinks. These kinks may include paraphilic infantilism, omorashi (also called wetting), and BDSM. When combined with paraphilic infantilism, the fetish is often called adult baby/diaper lover or AB/DL for short.
