It wasn't meant to sound fair.
You must remember that we are govern by norms dicated by our society. You are feeling this unfairness is because we are taught monogamy in our kind of society. Should you grow up in a different settling where polygamy thrives and is the norm dicated by society, then it's different.
And ultimately, we must recognise that man and woman are indeed different.
Without wisdom (like animals), males only task on earth is only but to propagate and ensure the survivability of the human race (male is to spread its seed while woman is to breed). But our psychological state refuse to accept that this is the reason for our existence - we believe that there MUST be other reasons why we are here. So you have most religion telling you that God has a role for you on Earth, we should have a fulfilling life (perhaps a mission?) and everything else started streaming in. And you have people like me preaching on how vital Love is - the backbone of any union.
This is how a male functions in dormant state. It is only purely because of our higher self that we prevent ourselves from degenerating into our animalistic instinct. Psychologically speaking, they would probably say that it is because of the Id, Ego and SuperEgo thingy, however, in the end, it's all the same.
Should we remove all our boon as a higher being, in the end, we realise that we are but animals. And WILL react accordingly to this biological nature. Even though man are indeed higher being, this animalistic, masculine instinct lies hidden in our subconscious. With wisdom, we will be able to tame it and be truly human in our behaviour and mindset. If not, man will just heed to its animalistic, inner calling. He will only be a 'male' and not man in humanistic term.
