What's your definition of quiet? Like you just don't talk in conversation? You're not outgoing?
A quiet guy is NOT a bad thing, but it depends on what the woman is looking for in a man. Some women like their men settled lets say, and some women want a man who will talk, hold a conversation for awhile, one whose outgoing, a social guy.
So, it all depends on the gal! But being "quiet" is not a bad thing! My husband I would say is a quiet man.
