Every religion and culture changes its nature over time. The India of the Kama Sutra had a severe turn toward asceticism. Often, there are global trends, so if Christians in the West are doing one thing, there is a cross-infection going on and a parallel movement elsewhere in the world, which may not necessarily be dependent on what one or the other is doing, but on the internal logic or evolution of thought processes. The movement toward patriachal modes of thought was based, most probably, on a semi-scientific insight regarding the one side of the dialectic with regard to insemination. So we proceed — semi-scientifically and intuitively. Often we emulate each other’s bad habits, not just the good. Sometimes, there is a sudden shift and what was mostly good can take a turn for the worse.
