Is it normal he acts like this to me?

This guy growls at me or maybe more of a sneer, and I've heard he likes me. Do boys growl sneeringly when they are turned on? Also maybe he's worried i don't like him, therefore he sneers at me. He seems scared to talk to me coz when he sees me he goes the other way or crosses over the road. So seems he's a little insecure. I even saw him break into a run once when he saw me coming up the path. He looked terrified too. So sweet....Also what's good is that he's quite close to my height, I'm 6ft 5 which is big for a girl, and he is about 5 ft 10, so its not too bad. I am also on the mixed wrestling team and I know men like that. I see the way their eyes dilate with horniness when I come near, even their knees shake. There hasn't been a man yet who has been able to keep me pinned down.
