Is this normal for a father to do?

I grew up with this but I have always hated it, I don't know why but it makes me uncomfortable but maybe I am overreacting? Whenever I am out with my family and we are walking somewhere my dad will put his hand on my lower back and I mean way down there just above my butt. He does that to guide me to walk beside him so we are walking directly beside each other or if I happen to be walking a few feet away from the group. But I don't like his hand going that low, it's so close to touching my butt that it disgusts and disturbs me at the same time. Do your dad's do this to you and is this normal? Sometimes people look and think we are dating at least that's the impression I get by the way my dad holds onto me and pulls me around like that. I have gotten double takes and disturbed expressions from people who are paying attention and it's embarrassing.
