Would you rather want to wait till marriage to intimately know your partner or will you rather know everything there is before marriage?
According to the prevailing law of our country, we can never choose a girlfriend before marriage, especially in our country, we can have physical relations after marriage. Having physical relations before marriage is definitely considered a crime socially and stately. That is why it is not possible to choose a partner before marriage in our country. We can choose our partner with the consent of the family and after marriage, we can have physical relations with you and it is known whether she is mentally fit to live with a man.
The sex laws of each country are different, some prohibit sex before marriage, some allow it, even women have children but are still unmarried, maybe in western countries this is commonplace, while in our country this is a bad crime.
I'm not going to criticize anyone because it's their right with their own country's rules --- so my custom and the government's rules mean that sex should be possible after marriage and that's much better for us.
Constitutionally some countries prohibites sex before marriage but such laws do not stand because of the corruption in the world right now, before such Constitutional restrictions has major effects on citizens but now such laws are easily bypassed as there is no one willing to make an expensive mistake that will keep hunting him till death.
Not that am pushing to convince you on having sex before marriage but you need to ask yourself this question, can you bear it if sex becomes the reasons behind your marriage failure as 80 percent or failed marriages all happened because of a man's inability to satisfy his partner.
Sticking to your said law on prohibition of sex before marriage are you telling me that all single ladies in your country still have there virginity intact or you are only saying it to prove a point.
