People can't behave themselves "recently"? Do you think there was a magic time in history where humans ever "behaved"? As far as I am aware, people have been fucking since they were biologically capable of it and many societies haven't been prude about it. (The Kanamara [Penis] Festival is probably a great example.)

The reason you got down voted is not because you said something controversial, it's because it's a comment that makes zero sense and is extremely out of touch.
