I'm not a pedophile but I'm curious if a person would still be considered a pedophile if in their sexual fantasies they imagined that they were the child and an adult was having sex with them? Because personally I wouldn't consider that pedophilia, to me pedophilia requires an adult instigator of the sexual activity.
A few years ago there was a legality controversy on a paraphilic infantilism story website with the U.S. government considering many of the stories to be pedophilia even though the readers were imagining themselves as the child being sexually used by adults.
