I have a Theory about women: I think you are ET´s. Yes, you came from another galaxy. In some pre-history moment your spacecraft had to do an emergency landing on our planet because you´ve forgotten to fill the radioative plutonium tank. Once you got out, leader´s wrist computer conclude after some seconds that there was no inteligency life in this planet.
The high council primarily installed decided to organize some expeditions to recognize our climate, plants and animals because you were hopeless to go back home. An advanced group some miles away were surprised with a scene of some hairy corpses animals who were executing a kind of ritual. Males eating their females (literally!). You discovered later that males did so because they didn´t know what better do with his females. The problem for exotic animals was that females were up to be extinguished.
So your leader have an idea: "bodies of this animals when shaved looks like miniatures of our males and our scientists discovered a compatible genetics". Then she pronounce the famous historical phrase: "who doesn´t have dog hunts with cat".
So your ancestrals decided for substituting the females of that kind (that they solved to call "Men"). Not before teaching them some civilized practices. Men enjoy a lot!
Another decision you´ve taken then was to pretend you were so stupid as females you substitute ("but we´ll take care of children education or future generation of women will never can go back to our beautiful planet").
An strange thing started at that time. You began to bleed once a month (I believe this was caused by a kind of allien "banzo")
