Do guys let any woman rest her head on his shoulder or chest? or is it an attraction thing?

I have a crush on my friend who randomly one day decided to start hugging me and it has always been a hug around my waist with interlocked hands.

But recently he has been letting me rest my head on his shoulder and chest.. occasionally he will put rest his head on mine when I do this.
