They think I'm lucky

Ok so I am 14 Years All of my friends have a much smaller bust to me,me being a 36ff and them being a a-d, In my body shape I look a lot older but not in my face,My friends say I'm lucky but I don't feel it I feel like I'm in danger every time I go out guys shouting at me from there cars and asking me how much    It's not about the clothes I wear I don't wear anything revealing, But all of my friends can wear crop tops and shorts in the summer, I cannot do that as my mum thinks if I dress a certain way that I would get a lot of attention and I don't want that,i just need advice about the situation that I'm in
