The reason is that a strong sense of humor conveys all of the attractive traits of your identity to a woman. A man who can laugh easily at the world and who isn’t afraid to laugh at himself conveys a sense of non-neediness. He also makes women feel good around him and, therefore, more secure. A man who is very serious and unable to laugh at himself or the world conveys that he is heavily invested in the perceptions of the world around him and is therefore needy.
