Men Being Polygamous- By Nature or By Choice?

A very sensitive and perhaps controversial question. It would be unfair to quote that all men are polygamous, so lets just say that majority of them are. That's not to say that there aren't polygamous women, we are just wired differently. Now the next question would be- is it by choice or by nature?

It's indeed difficult to prove from a biological point of view that men are. From a scientific perspective, it benefits men by having a lot of offspring. The human race just like all other beings needs to procreate to ensure survival of its species. The more offspring they have, the more they are able to spread their seeds and their genes live on. By staying with just one mate, they won't be able to spread their seeds since they have to wait 9 months until they can have more babies.

However, I would argue that men to a certain extent are born to be polygamous. Some men only use this guise in order to cheat on their women which is downright unfair. With this in mind, I would say that most of them are polygamous by choice.  Most men want what they can't have. And once they have it, they want more.  Could it be that men have this irrational need to always be in control even though they never will be?  I would agree that the male biological imperative is a bit different from the female and that would lead to men being more likely to engage in sex whenever the opportunity arises.
