Adult babies are among the stranger callers to phone sex lines, they are adults with no medical reason to actually need to wear diapers, they just find it comforting to wear adult diapers and relieve themselves in them and masturbate while wearing them. Some just pee in them, others pee and have bowel movements in them, some just cum in them. There’s been several callers over the years into this fetish I’ve spoken to, and ones into it in varying degrees. One actually sought the help of a psychiatrist he was nearly suicidal over his upset at being involved in such a fetish but he couldn’t stop himself from doing it, the doctor said he wasn’t really hurting anyone by doing it, so just to accept it and not become distraught about it.
Some will keep it a secret from family and their spouse and only do it when they can be sure no one will interrupt them like on a business trip or rent a hotel to be totally private. One used to call and wear pantyhose and shit in them in hotel rooms, my thought was the poor maid to have to clean up after this character. He wanted to know if it was normal and ok, I said no, it’s really not, but again, you’re not hurting anyone so don’t worry about it.
Most keep it secret from their girlfriends and wives since it’s a pretty pervy fetish and they know it will not be well received, so they carry it out in secret and don’t let anyone know about it. Some go whole hog with bottles and the whole bit, not just diapers, like everything, there’s degrees to it some do and some do not.
