The only type of sexuality that has historical indigenous precedence among Afrikan people is heterosexuality or what I like to call Afrisexuality.
There is no legitimate archeological anthropological literary or oral documentation of homosexuality or any other form of sexual perversion among African people prior to the pathogenic colonization and cultural invasion of foreign peoples, namely those of Caucasoid lineage.
“Though often ignored or suppressed by European explorers and colonialists, homosexual expression in native Africa was also present and took a variety of forms. Anthropologists Stephen Murray and Will Roscoe reported that women in Lesotho engaged in socially sanctioned “long term, erotic relationships” called motsoalle. E. E. Evans-Pritchard also recorded that male Azande warriors in the northern Congo routinely took on young male lovers between the ages of twelve and twenty, who helped with household tasks and participated in intercrural sex with their older husbands. The practice had died out by the early 20th century, after Europeans had gained control of African countries, but was recounted to Evans-Pritchard by the elders to whom he spoke. The first recorded homosexual couple in history is commonly regarded as Khnumhotep and Niankhkhnum, an Egyptian male couple, who lived around the 2400 BCE. The pair are portrayed in a nose-kissing position, the most intimate pose in Egyptian art, surrounded by what appear to be their heirs and wives. This is contested, as many archeologists, including David O’Connor, believe these to two to be blood relatives, most likely twins.” — History of homosexuality: Africa | Wikipedia
