In traditional Chinese culture, it's very unethical to cohabit with a man or have sex before marriage. But now more and more young people who leave their hometown and working in big city like Shanghai,Peking, choose cohabitation. But not all of them tell their parents the truth. They know their parents still have old ethnic standard and will be angry with the truth.
Actually parents of the boys don't care so much than girls.
What's that about in your country? Especailly in Europe and USA.
Is cohabitation really very common? Is parents really don't care your daughter cohabit with boy? Is that depand on their age? What if the girl is 20 years old.
I'm 24 years old,and cohabit with my bf for more than a year, but my parents don't know that.
