I would caution that one personal example is not a fair basis to make a VERY sweeping generalization loaded with culturally-derived assumptions.
From what I've gleaned across the board, from historical to recent, poltergeist episodes could be centered around pre-pubescent girls but this concept never been clearly elucidated and CERTAINLY never has been established. In fact, some researchers have suggested the entire troubled family contributed (in whatever way - normal or paranormal).
Well no, which is unsurprising, as the whole phenomena has not been 'established'. Before we worry about anecdotal evidence of prepubescent girls being the most common focus (and why that should be problematic I can't understand) perhaps we need to establish what is actually happening. If anything.
As for culturally derived assumptions....my own experience supports the stereotype of adolescent boys tending towards horny and aggressive and adolescent girls tending towards hysterical and very susceptible to group pressure.,,,make of that what you will.
Perhaps young males can release their energies with fits of agression or destruction, whereas young females require the opportunity to group in public places in order to be annoying.
TL;DR Teenagers - deeply troubled, wildly annoying and a general affliction on society.
