See, we are the only civilization that has a sex smruti. So what u say is right. My personal point of view is that, this oldest civilization had a different aura of dimension towards sex and casual sex. A similar connotation could be drawn that in older days women were also allowed to choose a groom of their own and their was large scale awareness albeit limited to upper class but it was there. Ad far as freedom is concerned it was existent.
The only drastic change that happened was the start of 11th century where the very definition of our laws and way of life started to bxome diluted.
Since then, it became what it is which is described by you. Some draconian draconian and barbaric laws like sati, women suppression came into existence in that period. Whether u own it to foreign influence then which was becoming a periodic phenomenon by the invasion of outside culture or not, is debatable. But changes did happen.
Now you will agree that in 1050 AD condom and contraceptive pill was not there relating to a lower climb in the number along with the fear attached to it. In 1250 along with moghuls kothas came into existence in India.
Sex was a purely dignified system on its own in our civilization. The kind of sex we see today is not what it was supposed to be according to this old civilization.
What we see today is misuse of sex in the name of freedom just how much we misuse freedom of expression and other things alike.
I have to quote a lady here to validate my position
