Weird stares

Hi, I have been getting weird stares everywhere for a while now. I look masculine, I wear boy's clothes but it's still quite obvious that I'm a girl if they look closely. Why is it that weird to wear boy's clothes? Why do people have to look at me so strangely as if I'm an alien or something..I'm getting sick of those stares. Sometimes I feel irrevelant to the society..as if I don't belong to this world.
