The author challenges the hypothesis developed by Caldwell and others that sexuality in Africa is inherently permissive, and that prevailing attitudes and behavior are primary reasons for the relative failure of family planning programs to reduce fertility, and thereby will be major factors hindering efforts to control the spread of HIV infections and AIDS. The article is in three parts. "The first is a summary of the thesis as presented by Caldwell et al., including their location of African sexuality and their conceptualisation of change. The second offers a critical response, focusing mainly on the problems of research into sexual behaviour and the christianisation process, with special reference to the case of the Kikuyu people, among whom, recent studies suggest, even where sexual activity may have appeared largely free of moral restraint, there was indeed a moral order.... Part three offers a new way forward." (SUMMARY IN FRE)
