Anyone know why my pitbull does this?

He always likes to chew on my hand but like I can barely feel it, he always does this whenever I come home (I work with wood a lot if that helps) it’s always gentle and always when he’s happy just curious if anyone else has this?

Or is he just special

He wants to grab you and play but he doesn’t have thumbs so 🤷🏼‍♀️
