Contain female sexuality? Yes, I know women have been out of control sexually for a thousand years - raping and pillaging throughout mankind - while men shrink behind their veils and chastity belts and those charming blue body bags the guys of Afghanistan are forced to wear.
Those guys in Afghanistan are TERRIFIED of female sexuality - that is why they make them wear those things - that is why a 9/11 hijacker was worried that a woman might touch his privates after the crash - that is the sad sick thing - they are scared of what normal men LOVE!
Plenty of rapine has been committed by married men. It was even expected of the soldier of Allah, or the Viking, for instance.
The married women were expected to behave themselves. It may be that male sexuality needs control more than female, but marriage exists more to control the female than the male. It gives the male sanctioned access; and it gives the children a father.
The double standard.
