Since this is in the religion forum, I'll elaborate. The Bible clearly tells us that the flesh is sinful by nature.
1 John 2:15-17 ESV / Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the desires of the flesh and the desires of the eyes and pride in possessions—is not from the Father but is from the world. And the world is passing away along with its desires, but whoever does the will of God abides forever.
Galatians 5:19-21 ESV / Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.
Romans 8:7 ESV / For the mind that is set on the flesh is hostile to God, for it does not submit to God's law; indeed, it cannot.
Romans 8:13 ESV / For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live.
2 Peter 1:5-8 ESV / For this very reason, make every effort to supplement your faith with virtue, and virtue with knowledge, and knowledge with self-control, and self-control with steadfastness, and steadfastness with godliness, and godliness with brotherly affection, and brotherly affection with love. For if these qualities are yours and are increasing, they keep you from being ineffective or unfruitful in the knowledge of our Lord Jesus Christ.
Believers have a choice to walk in the Spirit with God or give in to the desires of the flesh. There are only two choices. Sometimes we struggle and go back and forth trying to satisfy our desires. It doesn't matter if you're male or female, the choices are the same for all of us. From the scriptures above, the Bible gives us a great description of the spirit and flesh and it doesn't matter if we are thinking about cheating (or sinning in general) the flesh always wants to do what it wants to do. It doesn't take breaks or a vacation from those attributes because it is always the same. We battle our flesh all the time and some are more successful at it than others and some fall to temptation more than others. As for the truth factor, whether we believe it or not is irrelevant. The truth stands alone regardless whether you and I want to accept it or not. Amen.
