Having feelings for opposite sex is perfectly normal. Having said that, it’s abnormal to have sexual feelings & fantasizing of rapist boyfriends at the age of 15. No wonder we have such high figures of preteen sex & pregnancies in today so-called very-liberal society. By the way if you think you are a perfect parent but by what standards?
Being in love with materialistic & cultural icons is fine and Justin Beiber is part of culture. Are you confusing pop music with rapist boyfriend or hot n sexy cousin. I think you are. Better sit down and think logically instead of how you brought up and what you go through in your life.
