I disagree with you as well Drmana,not all couples indulge in promiscuous activities and in fact,many are loyal and faithfull to their partners.In our muslim cultures,young people are encouraged to marry so as to avoid indulging in sinfull behaviour,as intimacy outside marriage in Islam is forbidden,and by young people i meant mature adults who know what is right and what is wrong in their lives,there is even a HADEETH or a religious teaching that encourages young,unmarried adults to get married.Enough said.
