Unfortunately most people who look at polygamy from the outside the first thing that crops in there mind is sex with more than one woman.As if the man is going to orgy with other women24/7 for the rest of his life.I have friends who have more than one wife, many as much as four and to tell you the truth there is a lot of responsibility there and if a man feels he can handle that responsibility then why not.Sex is part of a marriage, that binds it and keeps it together but it does not mean that if a man takes another wife all he would be doing is having sex 24/7. that is just part of the equation, I feel for a man who loves sex and has an appetite even if he has one wife he can be happy however she must be able to keep up and deliver the goods in the boudoir. This man who feels he can afford to have more than one wife has to bear the responsibility for looking after the wife too.If he has kids with here and so on.
People should stop looking at polygamy with blinkers on taking it as just an orgy with other women.
One thing i can tell you for sure one very good mate of mine has 4 wives. He is in his sixties and looks younger than me. I suppose it is true that in order to keep these women happy one has to look after oneself more, look better, eat healthier in order to be able to fulfill their desires because women have them too and sex is not just for men.And also you more than one women caring for your well being,making sure you look good , eat well, looking after you in times of illness and so on.
