derived from the word "ginomai", meaning "become" (written as "γίνομαι" in greek), ginomaiphilia is a fetish where one who has it may imagine themselves as a different character, usually a fictional one, and feel horny arousal. one who has ginomaiphilia may also imagine the character they feel aroused to imagine to be in a specific situation, wearing specific clothing, and/or is in a specific mood.
