I agree with everything that Orphan said in his reply but would like to add maybe one or two things. First of all, if you pray that God help you to overcome temptation, He certainly will. Jesus prayed, "Lead us not into temptation, but deliver us from evil (or the evil one)". If our heart's desire is to follow and honor God, he will always be there for us. Second, learn to recognize the situations that are potentially dangerous for you and then learn to stay away from those situations. We can all live the way God wants us to live if we just use our heads and do what we can to deal with temptation and all the tricks of the devil. And this doesn't mean that we need to stay away from boys, it means we learn to recognize our limitations and weak points.
