Sex positive person here and I totally agree - until the massive sites in this area of the net (PH, Xhamster, etc.) actually dedicate themselves to eliminating categories like "teen", "barely legal", etc. then this fetishization is just going to be a continous cycle.
Many are also borderline obsessed with making the distinctions within pedophilia (hebe vs pedo for example), despite how it all boils down to the same thing "the fetishization" (often of young girls barely into puberty) "of taking someone's virginity" despite how virginitiy is purely a puritanical concept.
Society as itself HAS to change. How we make certain subjects taboo HAS to change. Parents HAVE to be willing to have sex positive conversations with kids involving consent, sex, etc.
