Actually there are alot of verses in the Bible that condemn immorality.

example:
1 Corinthians 6:18 (New International Version) - Flee from sexual immorality. All other sins a man commits are outside his body, but he who sins sexually sins against his own body.

Ephesians 5:3 - But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God's holy people.

When I express my opinion it's all based on my believe on what I learnt. I don't set standard for other people and I certainly don't want to judge them (sapa lah daku ini...). These doesn't mean I'm fanatic (I think). I still associate with my friends despite their value and believes. But I still draw the lines between what I can do with them and what I can not. it's a matter of personal choice really, and I tried my best to make my personal choice as close as possible with what I learnt.

Klu diperkosa lain lagi ceritanya, udah jelas namanya bukan immorality lagi, tp dipaksa. klu sex before married kan yg dimaksud disini atas dasar suka sama suka for fun reason.
