It invites a question worth asking, but for a man his age, he could be referring to college girls. I would consider it likely that Epatein had custom experiences for most every prurient interest including young but safely above the age of consent for non-pedophiles.
It's possible, but look at Trump's history. He likes women on the younger side too. Not pedo style, but the "I may be old, but I'm also and rich so I can get hot 25 year olds" type. It certainly begs the question since Trump has a history of dating a good clip younger than himself, why it was necessary to call out Epstein?
