4 REASONS TO WAIT:
1.Biblical reason
Man are created in the image of God. We are different from animals. Sex drive needs to be tamed before marriage. Sex is a gift, designed by God within marriage. It is not a punishment or some kind of forbidden fruit. It is holy. "All other sin a person commits outside the body, but the immoral person sins againts his own body." (I Cor 6:18)

2.Social reason
No man is an island. Premarital sex is not just two persons' business. It involves others such a as families, school and the whole society. Premerital sex causes social problems such as illegal abortion, venereal diseases, teenage pregnancy, teenage mother, etc. The government has to spend large sum of money just to deal with all these social issues.

3.Moral reason
It is selfish act. Sex before marriage easily becomes an irresponsible act. You want to have a pure spouse in the future but now you go around to play with others' future spouses. This is contradictary. Sex is like a gift to everyone. When you have relationship with someone before marriage, it is as if that someone opened the present that was meant for other, in this case, your future spouse. That someone opened the present, played with it and then wrappe it up again. The present would not be in good condition anymore. There is no condom in the world that can protect your heart from broken. And it is impossible to pretend that nothing has happenned between that person and you after the relationship.

4.Pshychological reason
Sex before marriage affects the development of the whole person, like spiritually, morally, emotionally, intellectually, and also relationship with others. Sex has such strong impact on young people that once tried during dating, you might want to do it everytime. It dwarfs the healthy growth of a relationship. It also causes distrust, fear, suspicious in future marriage. It spoils the significance of honeymoon.

What are some ways to prevent premarital sex?
--->Read good books, have knowledge and don't be naive.
--->Commitment to wait for true love, that means no premarital sex before and no affairs after marriage. Make up your mind early, even before you start any dating. It is your mind not your body that yields the first tempatation.
--->Set up and draw physical lines if you are dating. Make mutual agreement where to touch and where to stop. There are different stages of physical touch: kissing, patting outside the clothes, and taking off clothes. Both of you have to decide where to draw the line wisely.

What can you do if you had done it?
Repent and don't do it anymore. God still loves you. Tell someone you trust. Ask him or her to help you.

"No premerital sex for me, these are what we've been taught as a Christian. I quoted this from The Chinese Methodist Message. I vow to make sure I obey it, THOU SHALT NOT COMMIT ADULTARY"
