I don’t want your last name

This is a genuine question I’ve been wanting to ask. Would a man be offended if his wife did not want to take his last name? I don’t see myself getting married any time soon so maybe this will give me time to reflect and think. I just don’t see myself changing my name once getting married. It has nothing to do with the person or how much I love them. Would this be a problem for you personally? Is it such a big deal? Why so?
