Flee from sexual immorality. All other sins a person commits are outside the body, but whoever sins sexually, sins against their own body.

Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed, which is idolatry.

For of this you can be sure: No immoral, impure or greedy person—such a person is an idolater —has any inheritance in the kingdom of Christ and of God.

Galatians 5:19-21 NIV
The acts of the flesh are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
