Adult Babies
Infantilism is the desire to wear diapers and be treated as an infant. A person characterized by it is referred to as an infantilist; one who engages in infantilistic play is known as an adult baby (AB). Adult babies and diaper fetishists are collectively known by the acronym AB/DL. The majority of known infantilists are heterosexual males.
Club Diapers is a good site to join and get a feel for the fetish.
