Calling herself a "former sex worker," the well-liked teacher has been shockingly up front about her past -- posting online accounts of her sexcapades in Mexico and London.
But in her boldest move, the 30-year-old posted an essay this month claiming she also had been a pros titute.
"From October 2006 to January 2007, I accepted money in exchange for sexual services I provided to men I met online in what was then called the 'erotic services' section of Craigslist.org," wrote Petro on The Huffington Post, using her real name and picture. The attached bio identifies Petro, who has an MFA in creative nonfiction from The New School, as a "former sex worker, researcher, writer, educator, and feminist."
It appears she managed to keep her shenanigans a secret from parents at PS 70 -- who were stunned by the revelation.
"I don't want nobody that used to do that to be around my kid," said Grace Ventura, whose son is in third grade. "People like that should not be allowed to be anywhere near children."
