I was reading an article which said that men are not naturally monogamous and as we know in some cultures it is perfectly natural for a man to have many wives. However in most civilised countries it is considered wrong. I currently watch a programme called "my Four Wives" which is based on a man and his four wives who live in the USA and call themselves sister wives. It's interesting but fraught with problems and there many children most of whom do not want to be in polygamous relationships when they are old enough to marry. Although they all call themselves wives he is only legally married to one of them and there has been a lot of jealously involved over the years, It's interesting to note that polyandry where a woman has many husbands or polyamory where there are multiple husbands and wives is not often heard of but it does exist in certain cultures but we have been conditioned to believe that it is better to mate with one person.
