Adult with a capital A

Ok..this is a bit controversial but I have been thinking about it for sometime now and I would rather jot it down. We say men and women are equal and the "good Lord" doesn't really discriminate between the genders...if that's so, then why is it so different during the procreation process....if a man is capable of procreating 30 days in a month, then why is it different for a woman??? Even if it takes two to tango, the twosome should enjoy equal rights and benefits all the way in an equal world, what say???
