Running prostitutes? You mean being a madame? There have always been those yes but the makers of porn movies, pictures, books, magazines, et cetera have been for the majority males. Hugh Hefner, Larry the Flint to name a few.
Hefner and Flint have a lot of women working for them, helping to recruit new young women.
A lot of porn is made these days by women.
btw, the only purpose behind my comment is to point out its not just a male problem. Women are producers of it and consumers.
