Proverbs 24:8-9

8He who plots to do evil
Will be called a schemer.
9The devising of foolishness is sin,
And the scoffer is an abomination to men.
-Proverbs 24:8-9

There is a line in regard to sin that we would do well to understand properly. Temptation itself is not a sin. You will not be held accountable for how the flesh entered in and desire wickedness. You will, however, be held accountable for how you interact with that temptation. Even entertaining it and planning wickedness is sinful. Our response to temptation needs to be death to self and denial of the flesh. As we give way to it and allow it to be entertained in our minds, we give the enemy a foot hold in our lives. You will see that it is harder to not fall into it. Be swift in silencing the flesh and its lustful desires. Cling to the Lord as though your life depends upon it, for it does.
