Former Bronx teacher Melissa Petro, who was forced to give up her teaching job after revealing she worked as a hooker and stripper, will pose for Penthouse’s February issue for a story charmingly titled, “Unrepentant Whore.” The ex-educator, who now makes a living writing about her sexy past, has mixed feelings about the pictures, in which she appears partly nude. The shoot, at New York S&M dungeon Pandora’s Box, involved Petro posing in the clichéd role of a sexy teacher. In a column for xoJane.com, she writes that the photographer’s “vision, as he explained it that day, was for the ‘hooker’ teacher to reclaim her power — to take the butt of the joke and turn it around. When the shoot was over, amidst my signing of releases galore — including a creepy moment when they made me take a picture holding up my ID — I felt a momentary panic . . . Is this something I’ll regret?” Petro says she feels empowered by it all: “A part of me likes being exposed — the more exposed the better.”
