Wierd situation..help..!!

First of all, you shouldn't have to change how you dress because some guy can't stop staring at your chest. That's ridiculous! Next time he does it, say, "I feel really uncomfortable when you stare at my chest. It's innapropriate and I want it to stop right now". That is not normal for him to do that in my opinion and I couldn't say for sure if he would try to touch you or not. Take a stand and tell him you don't like it and you want it to stop immediately. If he won't stop, tell a female teacher or school counselor that you trust. That can be considered ual harrment, believe it or not. You can tell your boyfriend but I would tell your boyfriend not to hurt him. That can backfire on your boyfriend and you too. You guys could end up in trouble and you aren't the source of the problem. I had really big in highschool (I was thin with big s) and got stared at a lot. Every time I told the boy to stop, he would. I usually said it in front of other clmates and that would embarr the kid enough to make him stop. I had to do that several times, to several boys, but every time I told the boy to stop it, he did. He might keep doing it until you stand up to him.
