Most people who work managing prostitutes are men, but some women work in this capacity as well, though rarely in street prostitution. Women are rarely called pimps, as the word implies male dominance - a woman who manages prostitutes is generally called a mamasan or a madam. (This should not be confused with the title of respect given to adult women in most English-speaking countries.)

Donald Goines From 1952 to 1955 he served in the army. During this period he got hooked on heroin. When he returned to Detroit from Japan, he was a heroin addict.
The next 15 years from 1955 Goines spent pimping, robbing, stealing, bootlegging, and running numbers, or doing time. His seven prison sentences totaled 6,5 years. While in jail in the 1960s he first attempted to write Westerns without much success - he loved cowboy movies. A few years later, serving a different sentence at a different prison, he was introduced to the work of Iceberg Slim (Robert Beck). This time Goines wrote his semi-autobiographical novel Whoreson, which appeared in 1972. It was a story about the son of a prostitute who becomes a Detroit ghetto pimp. Also Beck's first book, Pimp: The Story of My Life (1967), was autobiographical. Goines was released in 1970, after which he wrote 16 novels with Holloway House, Iceberg Slim's publisher. Hoping to get rid of surroundings - he was back on smack - he moved with his family to the Los Angeles ghetto of Watts.

True this. White women in particular such as Heidi Fleiss and those who run "Cathouses".
In Hollywood many of these "Madams" are also known as "Stage Mom's" lol!
