In some of the videos, you can see some of the women or girls squirming away, but this does not stop him as it would a normal person.
I wonder of it might not be closest to bullying. For one thing, he kind of seems to be saying to the men: I am so much more powerful than you are that I can do this freely with your wife/daughter.
I am tired of hearing people relate this to hugging. He is totally taking liberties, caressing and breathing in like that.
In essence, Biden's not much better than King Louis XVI in "History of the World"
Were Biden an average Joe (pun not intended) with no power per-se, the woman or the parents of the child would likely react, giving him a slap, or if the child's father was present, a punch in the nose. Since it's being done by none other than the Vice President of the United States, it's sloughed off as "Joe being Joe". And since no one has ever taken Biden aside to correct him on this, he's likely unaware of it as bad behavior.
I think he is fully aware of what he’s doing and knows from experience that he gets away with it because of his position...
Think about Sessions slapping his hand away from Session’s grandchild...
