Judges 16:1-21

Then Delilah pouted, 'How can you tell me, ‘I love you,’ when you don’t share your secrets with me? You’ve made fun of me three times now, and you still haven’t told me what makes you so strong!' She tormented him with her nagging day after day until he was sick to death of it." v.15-16
Samson was deceived because he wanted to believe Delilah's lies. Although he could strangle a lion, he could not smother his lust and see Delilah for who she really was. How can you keep your desire for love and sexual pleasure from deceiving you?
1. You must decide what kind of person you will love before passion takes over. Determine a person's character and faith in God are as desirable as his or her physical appearance.
2. Because most of the time you spend with your spouse will not involve sex, your companions personality, temperament, and commitment to solve problems must be as gratifying as his or her kisses.
3. Be patient. Time and observation often reveal what is beneath the pleasant appearance and attentive touch.
