Fornication is still a sin.
Is there a normal man who isn't guilty?
Yes.
Romans6:
21 What fruit then did you have at that time in the things of which you are now ashamed?
For the end of those things is death.
22 But now, being made free from sin, and having become servants of God, you have your fruit of sanctification, and the result of eternal life. 23 For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.
