Sex has fascinated mankind from the very beginning. While most conservatives argue that sex has become too central in today’s liberal-minded society, a far cry from the pious nature of our ancient forebears, some of the sexual practices of the ancients were too bizarre even for our modern standards.
#1. Sex with another man’s wife
The ancient pre-Islamic Arabs were into a strange custom known as wife. It was practiced mostly by families of low rank who wanted more prestigious offspring to ennoble their line. Men of distinction who possessed desirable attributes were allowed to have sex with another man’s wife. Children born out of this custom were considered the children of the husband, not the biological father. The husband would simply send her to the home of the chosen man, where she would stay until she got pregnant. In order for the husband to claim that the child born from the union was his. He must abstain from sex during the time his wife lived with the other man. If the husband was able to contain himself during that time, the child was considered his in the eyes of the community.
