Usually in Indian society, they still think that men shouldn’t do the household. A man is not made for cooking food or mopping the floor. But you don’t have to listen to them. It’s a good thing that you are helping your wife with her household chores. A house is a place for both husband and wife. So, they both are equally responsible to keep it clean too. You love to cook and if you are letting your wife rest while you are cooking. Then there is nothing wrong with it. Actually, your sister and mother should be proud of you rather than humiliate you.
