Even talking about how much you want a penis to a 13 year old in the US is a sex crime.
And, as long as you've gone there Free,
I think that people are attracted to equals. Equal age, equal mental levels, equal life values and all that.
So, you have two choices here. One, if this is an attraction of equals, then Ellwood is about 13 when it comes to emotional/mental age. Oh, don't like that. Well if El is really an 18 year old, looking to date (his word) a 13 year old, then he is a predator, a much older person looking to exploit a person with much less experience and much less aware person.
Neither matter, if El is just at a mental age of 13, and his attraction to 13 year olds is therefore natural - it does not matter under the law.
