For ages birth control played a great part in this , for what's the fun in your life when you have already 6 kids to feed when your only 21 . Naturally this power to give birth , or not , was in the hands of the females . And like in nature , a mother will choose her seed's with care and wait for the proper guy . It isn't that long ago , like my parents both come from family's of 9 children or more .
But now we given this power away to a medicine company , witch gives woman the freedom you speak of ,... free sex . Now this rate thing , after ages of difference practice , will take some generations to wear fully of .
Amazing , is this the age off Aquarius ? ,.. free sex for the lady's ! ,.. still i am looking for a downside to all this , but as a man , i didn't find any yet . ;-)
