You’re right about that minor detail, I must have misremembered - because it’s actually multiple minors who have spoken up as victims of his predations:

On the heels of the damaging videotape on which Trump and former Access Hollywood host Billy Bush salivated over Days of Our Live actress Arianne Zucker, and joked about sexually assaulting women, came allegations that Trump entered the Miss Teen USA changing room where girls as young as 15 were in various states of undress.

Mariah Billado, Miss Teen Vermont 1997 told BuzzFeed, “I remember putting on my dress really quick because I was like, ‘Oh my god, there’s a man in here.'” Three other teenage contestants from the same year confirmed the story.

He’s so prolific in being a known rapist and molester that Wikipedia has a page for the receipts:

https://en.wikipedia.org/wiki/Donald_Trump_sexual_misconduct_allegations

…and their issues with the page (from the tags at the top) are too often it uses Trump’s own admissions as the source, and that it needs to be updated. Both of which indicate just how into doing this sort of stuff he is.
