Donald G. Mathews refers to the days of Jim Crow, and white man fears of superlative black powers in the sexual realm. "The whites' belief that blacks' sexuality was far greater than their own and that the license of such libidinous creatures had to be controlled." [ Religion in the Old South, p 71 ]
The notion that blacks could be seized by uncontrollable fits of sexual passion was derived in part from the traditional picture of Africa as a land of licentiousness. As early as the 1840s, Josiah Priest, one of the antebellum proponents of the Biblical argument for slavery, attempted to prove from Scripture that the descendants of Ham had overdeveloped sexual organs and ... were guilty in ancient times of all forms of lewdness. 'The baleful fire of unchaste amour rages through the negro's blood, more fiercely than in the blood of any other people,' wrote Priest, 'inflaming their imaginations with corresponding images and ideas . . .' Later the racist propaganda directed against emancipation and Reconstruction laid heavy stress on the contention that freed blacks had an uncontrollable desire to violate white women. There is little reason to doubt the conventional notion that a fear of oversexed 'brute' Negroes has been a constant and deeply rooted feature of the white racist imagination. [p 276]
Frantz Fanon in his Black Skin White Masks digs into much of the excitement, the taboo, and the sheer sexual power of the attraction between white women and Black men. Negroes in the traditional lore of the white 'grapevine' were thought to have tremendous sexual powers almost primal in their magnetic enormity (p 157)
Fanon alludes to the psychological conditions out of which the Black superiority myth arose (white man's feelings of sexual inferiority) p 159
Fanon (p 169) notes the deep rooted connection in the collective mind, that the Negro stands for sex (p 160)
"Negroes symbolize the biological ..... he is hot-blooded ...blood is strong ... he is tough" (167)
Fanon quotes Michel Cournot, Martinique 1948 (p 13-14) "The Black man's sword is a SWORD. When he has thrust it into your wife, she has really felt something. It is a revelation. In the chasm that it has left, your little toy is lost. Pump away until the room is awash with your sweat, you might as well just be singing. This is good-by .... Four Negroes with their cocks exposed would fill a cathedral. They would be unable to leave the building until their erections subsided; and in such close quarters that would not be a simple matter." [cited by Fanon 169]
"For the majority of white men the Negro represents the sexual instinct in its raw state. The Negro is the incarnation of genital potency beyond all moralities and prohibitions. [From this, the white woman comes to] view the Negro as the keeper of the impalpable gate that opens into the realm of orgies, of bacchanals, of delirious sexual sensations."
Fanon writes: A white woman who has had a Negro lover finds it difficult to return to a white man. Or at least it is so believed, particularly by white men [Fanon, p 171]
