Does not matter Again there is a source in the article and plenty are in the Pedophilia article Pedophilia being a controversial topic does not stop the fact that it is not the same thing as ephebophilia There being many ways of defining children does not stop the fact that pedophilia is a sexual preference for prepubescent children Being romantically sexually attracted to a 17 year old is not a mental disorder especially since 17 looks no physicallly different age wise than 18 If being romantically sexually attracted to mid to late teenagers is a mental disorder then it would mean that many normal people have a mental disorder Brad Pitt as well since he dated a 17 year old old Juliette Lewis when he was in his late 20s Furthermore ephebophilia is the primary or exclusve sexual preference for mid to late teenagers which is different from a random romantic sexual attraction to teenagers anyway but it is still not a mental disorder and is still not pedophilia
