Is he attracted to me or not?

I have a huge crush on my one of my guy friends. He comes over and talks to me , teases me etc..but he never hugs me or mages me like he does with all his other platonic girl friends. He wont even hold my hand! But he will brush his leg against mine when we are sitting near each other and he will stand right next to me brushing aginst me or leaning against me when we are in a group setting. So...is he attracted to me or not. And if is why is so careful about not hugging/maging my shoulders?
