The answer is really, really simple. Men find it much more fun to control women than to control themselves. Religion, which men invented, is the perfect vehicle for this power. Deep down, of course, men's worst fear is that the children they spend time, money and affection on, might turn out to have been fathered by some other man, so controlling women is vital to their manhood.
Just imagine what a world we might live in if only men decided to control themselves instead of women !!!
