It is mainly because of the media where they come to know all about sex. That too the world of pornography makes many to think that the world is full of sexual activities and nothing more. Added to that now plenty of commercial sex workers (flesh trading) waiting to hook up and that is the reason teenager indulge into premarital sex.
I'm sorry no, teens have always had sex and that has nothing to do with commercials, society or porn. Not even when you are addicted to porn, which is unusual in teens, does it have such effect. They fall in love, are curious and their hormone levels have never been higher. They are horny just like adults and many are fully aware of that they might not get married. There are no guarantees in this world you will ever meet someone and when you fall in love for the first time it feels like it will last forever. Sextraders have always been there as well and the majority of kids do not go to prostitutes. Just because you are well educated about sex or have acess to birth control does not mean oyu will have sex. That is not how people function, teens or adults. It's just a myth creatyed to have something to blame on when teens have sex. It's perfectly normal to feel those things and have sex.
Premarital Sex and Religion The Catholic Church teaches that premarital sex is wrong, yet it is still widely practiced around the world. The reason marriage was created was to join two people of the opposite sex together in a holy sacrament that would make the couple one. God’s reason for marriage is quoted in the bible when he said, “For this reason a man shall leave his father and his mother and be joined to his wife, and the two shall become one flesh” ;. The Sacrament of marriage is one of the most sacred Sacraments in the Catholic Religion. By performing premarital sex, the couple is breaking a covenant with God and is performing a sin. Marriage is the joining of a couple in the eyes of God and in the eyes of the State. When two people are joined into marriage they become on in flesh and one spirit. Sexual intercourse within marriage is for this reason good and of great blessing both to the couple, to the family and to the church. However, outside of marriage it creates a conflict of body and soul. This conflict may not at first be evident but later it can result it real soul damage occurring between the two people involved. God tells us that we should control out bodies and our lusting, “It is God's will that you should be sanctified: that you should avoid sexual immorality ;that each of you should learn to control his own body in a way that is holy and honorable, not in a passionate lust like the heathen, who do not know God”1. By performing premarital sex we are abusing our bodies and our souls. The pain that premarital sex puts on us is very evident. Physically premarital sex can lead to many things, such as pregnancy, sexually transmitted diseases, and other things that accompany premarital sex. Mentally premarital sex also hurts. Our bond with God is ruined, we lose contact with God and we are no longer part of the Church. Premarital sex goes against God’s law so our relationship with God is destroyed. Penance can heal our relationship with God, but the emotional ties that go along with premarital sex can hurt a person for life. Many couples that have premarital sex often do not stay together in marriage. Many people have strong emotional hardships that they go through after having premarital sex. Premarital sex doesn’t just lead to sin ;it leads to a separation of God and your family and friends. Sex is the sacred sigh of the covenant with God, when a couple has sex they are sealing the covenant with God. Breaking this sign of the covenant is one of the most harmful sins that we as a people can expose ourselves to. In order for us to enter into heaven God says "But among you there must not even be a hint of sexual immorality, or...
