I bet it sounds like everybody is trying to scare you off Icmeler, far from it, everyone has given you good advice, probably just like your parents have, basically just do what you would do back home, just what most people have told you, ie you probably would'nt wander around late at night on your own at home etc, don't worry people are only saying all of this because you are pretty young and don't want anything to happen to put you off Turkey and Icmeler,
Icmeler is a fantastic place with lots of great bars and restaurants and mostly very nice people,i am sure you are going to have a great time and want to go back again next year.
