Is it normal i sway my hips from side to side whenever i cook/clean/etc.?

So this one time i was cooking and i needed a bowl, it was too high up in the cabinet, so i called my brother to come reach it for me. he stood behind me and got it for me, but he told me that i was wiggling my hips against him. i didnt even notice that i was doing it. its not just when i cook though, my bro said he notices me doing it a lot whenever i do things, like cleaning or playing with the dog and stuff. am i normal for doing this? should i try to catch myself wiggling my hips like this and make an effort to stop?
