When you hug a guy and he says your hair smells nice what does that mean?

Well, when a boy really likes a girl, he finds her scent almost hypnotizing. They could follow you sniffing all day! And when I say scent, I don't mean perfume. Some boys like perfume on girls, but the scent I'm talking about is the natural one girls give off. It's kind of a human instinct thing, to like the smell of someone you like. Or maybe he just likes the way you smell as a person, not in a sexually way. It's either an "Oh, I love everything about you, including how you smell!" or "you just smell good." thing. But that boy must be really laid back or having the guts to tell you that. Most boys don't tell girls their addiction to scents. Hoped I helped!
