Catherine Hakim is a blackpilled sociologist who wrote Honey Money: The power of erotic capital, which explains how to take advantage of sexual sublimation. She argued that there has developed a sex deficit since the sexual revolution that primarily affects men. She also claims that men have a libido that is one average twice as high as women. As such, she has proposed fully legalizing sex work. The popularization of the term "sex deficit" can in substantial parts be attributed to her. She uses the term in the context of male sexlessness.
