That… is terrible. I hate this. It’s pure harrassment and yet no action being done? The blame is shifted on the victim? 
OP, I’m sorry, but your school… seems horribly unfair. 

e-excuse me? That's so fucked up. I absolutely hate it when people use the boys being boys thing or when your parent say a boy likes you when they are straight up bullying you. We can't control how our freaking bodies look we were born with them. But other people can control how they act. that is straight-up gross. And to tell the girl not to tell her parents when she's been harassed? Ohh my god this is so fucking stupid. I mean it's the same with uniforms. Like being dress coded for having a dress blow your knees cus guy can't control themselves apparently. God this is infuriating.
