One thing I have been thinking about lately, and that would be at least one new category we could use.
One of them available is "Pedophilia", which incorrectly in common use has become sexual relations with anybody under the age of 18. But that is actually incorrect, as it is actually with anybody that had not yet reached puberty. Meaning anybody roughly up to the age of 11.
Then next is Ephebophilia, those in puberty. Usually between 10 and 14.
But the one I think could be added is Hebephilia. That is teens that are past puberty. 15-19, but 14 could also apply. Especially as this works both ways, unlike the "teen siren" category.
As it states here, that is a teen girl going after an adult male. But an ephebophile could be an adult male going after a teen girl, or even an adult female going after a 15 year old boy. Or in some cases, even an 18 year old teen going after a 14 year old teen.
Just food for thought.
