Question:
What if it happens before marriage, is your life a total failure from then on?

Answer:
Losing your virginity before marriage is a terrible sin. Fornication is an especially harmful sin which causes adverse effects “against” the body that other sins do not cause. “Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body” (1 Corinthians 6:18).

However, though you must reap God’s government for your sin (Galatians 6:7, 8), if you stop doing it until marriage, and repent, God will forgive you (1 John 1:9). He will thus give you victory over the flesh (Romans 7:24, 25; 8:3, 4).
