Lewis Nkosi is a South African black writer who fought against apartheid. His first novel, Mating Birds, is the story of an educated black youth, awaiting death for the alleged rape of a white girl, with whom he claims to have a muted love affair across the segregated beach. The narration can be read as an attack or invective on apartheid, the politically racialist system. This paper also studies Toni Morrison’s Beloved, one of the true pictures of black female in the History of Slavery in America. Illuminating the distorted maternal love of a black mother, Morrison wanted to present fundamental problems of slavery through the work. The physical and sexual violence, exploitation of labor force, depredation of a child, all these had critical influences on the (sexual) identity of a black female as a woman, wife and mother. Comparative analysis of these two works reveals that black female sexuality is different from both that of white female and of black male. The thing which this paper reveals is that existing western white-oriented theories are ignorant of the racial, ethnic, and cultural differences when it comes to explaining the development and role of the unconscious, the characteristics of sexualities, which shows their ignorance about lives and cultures of non-western, colonial coloured people.
