Last week Rogan compared himself to the boy who never grew up, saying he feels better than ever at 38.
The comments came ahead of his grudge fight with Sexton at the Odyssey Arena, Belfast, on November 6.
It's a mouth-watering rematch of their May fight, which Sexton won thanks to a controversial swollen-eye stoppage in the eighth round.
And the Commonwealth heavyweight champion has blasted Rogan over his Peter Pan quotes.
"It wouldn't surprise me if Martin started saying that he's been getting advice from Tinkerbell next," said Sexton.
"It would be understandable because he seems to be away with the fairies if he thinks he can beat me,
"Peter Pan was one of my favourite books when I was little, and the character Martin reminds me most of is one of the Lost Boys.
"He didn't have a clue what to do when he fought me in Belfast.
"He had one good round and hasn't stopped moaning since about being hard done by, even though I bashed him up and made things look easy.
"I boxed his head off and I'll do the same in the rematch. I'm much fitter now than when we fought in May, and I'll have no problem going the full 12 rounds if I need to.
"But to be honest I don't think that will happen because I'm going to break Rogan's heart.
"I out-boxed him the first time we fought, and I'm going to do a number on him again this time around."
