Narrowly and simply eros means love, for body or for mind, whereas lust is lagneia. There isn’t a perfect specific expression, but none of these feelings or specific ouht become a mental or social disorder.
It may be the clinical definition but clinicians abuse foreign stems and loanwords. It means “kidfriendship”, friendship with a kid. Sexual attraction to kids (not children which is incest, tecna) is eròtopædia. Clinicians also say you must be 16 years of age to qualify which is bullshit. Otherwise lots of kids should qualify.
