A humiliatrix is a specific type of female dominatrix that is particularly skilled in the art of humiliation.
A humiliatrix might be skilled in either sexual/ erotic humiliation, or in real-life humiliation. A humiliatrix differs from a traditional dominatrix in that a dominatrix inflicts physical pain on the sexual partner while a humiliatrix inflicts psychological suffering. A humiliatrix might blackmail their partner, inflict stress, and mental anguish. She may also use physical humiliation techniques like face-slapping and spitting.
Financial domination (FinDom) refers to being a financial slave. It is most commonly seen between a willing male submissive and a female dominatrix. It is a fetish that involves being humiliated or demeaned by a financial dominatrix (also referred to as fin-dom), in exchange for money or gifts. It does not necessarily involve sex. It is said to have stemmed from the observations and eventual practice of Miss Marx, a professional dominatrix, who saw how some men get an instant hard-on when handing a woman money. She exploited this reaction, and eventually began a cult fetish.
The subject of financial domination is often referred to as a money pig. The act of extorting money or gifts from people is referred to as money slavery or wallet rape. Extortion happens through verbal abuse and sometimes consensual blackmail. A man who willingly subjects himself to this abuse is said to justify it by describing women as worthy of his servitude. Fulfilling this desire may be okay if one has enough cash to spare. However, that money might be better off used to pay for a therapist should this fetish affect day-to-day function and other people.
