God bless you. Do you know that Jesus said "one can commit adultery just by looking and committing that sin in their heart," even without the action. If it is one sin God tells us to flee it is lust. 2Ti 2:22 Shun youthful lust and flee from them, and AIM at and pursue righteousness, faith, love, peace in fellowship with all who call upon the Lord with a pure heart. In other words, if we are not pursuing the things of God, then sin will take its toll. God's word says "fellowship with those who call upon the Lord." Hang around godly men, not ungodly women. Not to be alone in a closed area with a woman, it does not honor the Lord. Since I am home sick, when my pastor visits, he comes with a brother in the Lord. He has a covering. For God says in His Holy word "shun the appearances of evil. Be alone behind a closed door with a man or woman is a playground for Satan, a playground for sin.
Joseph is one of my heroes, in fleeing fornication. He kept himself pure before the Lord for he loved God more than pleasure. He could not be seduced by the Jezebel spirit, but suffered for righteousness, for he pursued righteousness. Therefore cut off unholy relationships that put you in a position to be tempted, and drawn into sin. Tell Jesus about how you feel, fast about the spirit of lust. Feed upon the word of God. Join a men's Bible study, get into the word. God bless you.
