I didn't use the word nymphetishist in The Allure of Nymphets much. I heard the term for the first time in the movie Twinky (1970), which is about, Scott Wardman (Charles Bronson), a thirty-eight-year-old erotic novelist who married,Twinky, a sixteen-year-old schoolgirl to avoid being prosecuted for statutory rape; however, the writer regretted getting married after the nymphet wouldn't let him concentrate on completing his next novel.
The lyrics of the theme song suggest that schoolgirls should be "...dumb but pretty like a schoolgirl should be."
And it's worth noting that Charles Bronson's character did a great job of not being needy. He let the nymphet take their relationship to the next level. For example, it was her idea to get
married. He even used reverse psychology by saying, "It wouldn't last six months."
