Maybe NSFW: How come some men (men that are not necessarily pedophiles) like to consider the woman that they're with to be their "little girl?"?

There is a BDSM fetish called “age play.” If you google it, or look on a fetish website such as Fetlife, you will find many groups for age play, which usually means couples where the woman pretends she is a little girl (“Daddy’s little girl” or something like that) and the man plays the Daddy. I would guess that the majority of men that do this are not pedophiles but obviously there must be something to this if so many people are into it.

So the question is, why do some men like to consider the woman that they’re with to be their little girl?
