Oh! common people its been there. but everything was done behind shadows. So talking about sex is good. Look around the country most frustrated guys goto prostitutes end having that FOUR LETTER WONDER passes it on to families and kids. And thats the reason we one of largest in world for FOUR LETTER WONDER so better talk about it and practice safe sex. If u look back centuries u see v practiced it. I have read somewhere that in arthashasthra kautilya says brothels are required. (IF I AM WRONG I AM SORRY)
