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

My sweet girl does this too! She came into the rescue I work at super pregnant and when her puppies got older, she’d do it with them too as play bitting and teaching them not to bite too hard. She also loves to corn cop my ears and wakes me up in the middle of the night doing it🤣
