Gothamist has a story of a woman who worked in two S&M dungeons around the Herald Square area in New York City who wrote briefly about her experiences as working as a dominatrix.
She was asked if there were many haredim who were customers of these sex dungeons, and she said there were.
"Yes yes yes yes yes. Definitely one of my biggest shockers. Hasidism is a very restrictive religion in regards to sex. They don't fraternize with outsiders so they have to resort to sex workers," she said.
