No good will come of this thread.
It'll just be a yelling match between people who have an understanding of science and people who have no interest in information.
Most people are lazy so I'll give you all a chart.
nepophile (todlers, basically)
pedophile (pre-pubescent, has not undergone puberty) (you are likely talking 12 and under)
hebophile (pubescent, going through puberty) (12, 13, 14, etc)
ephebophile (adolecents, aka developed) (15+)
Then you start to get into adulthood.

It is abnormal to be any of these things, singularly, and abnormal to be attracted compulsively to anything with which you cannot reproduce. Therefore a "normal" male should be aroused by the 15+ and adult categories, and will sometimes be attracted to the 12+ category because the brain can be confused and unable to differentiate between whether or not she can conceive. If she looks as though she can, you are hardwired to be attracted. Your genetic make up has no concept of what state you are in, or manmade laws and other nonsense. Now... going around fukking 15 year olds is not the best idea. However, if you are not attracted to them you actually have a problem. In fact... if you are not attracted to developed girls that have underwent puberty and are genetically suitable canditates, than you are abnormal. You are a teliophile.
teliophile (matured, no longer developing) (adults)
It is also possible to be a gentraphile and attracted to women past the age at which they can reproduce. Old ladies...
Again, this is abnormal... cause she can't bear children.
TLDR; being attracted to anything that cant give you children is abnormal. Being attracted to anything that can is normal, but you better be prepared to get beat up by peole that never finished a biology course if you argue that point.
A "normal" person would overlap the categories ephebo & telio and occassionally dip into hebo/gentra by accident because a junior high chick has been ingesting bovine hormones or an old lady looks 25 despite being 47 like Stacy Dash.
