The first gift that Adam and Eve received was agency: ‘Thou mayest choose for thyself, for it is given unto thee’ (Moses 3:17). You have that same agency. Use it wisely to deny acting on any impure impulse or unholy temptation that may come into your mind. Just do not go there, and if you are already there, come back out of it. ‘Deny yourselves of all ungodliness’ (Moroni 10:32).
