Which is the most commoon one thing that the males are not satisfied with

MEN: They are never satisfied with the amount of love and care they get from their better halves and yearn for more. They always wish that she could have been more like this and less like that and stuff like that. WOMEN: They are never satisfied with the giving, they kind of give, give and give more to make their man home bound and love them more. Women pamper men like anything and men enjoy that. Hope you take this in right spirit.

As much as they won't admit it from my experiences I would have to say they are not satisfied with their life in genral.

Each other's nature. Women think that why cannot men thinks like them and men think that why cannot women think at their level.

The common sharing of unsatisfactoriness between both sides, male and female, is having involved with third party relationship. Will create tense situations and exacerbate the worse condition in relationships. Let say not for the above reason, another reason is about cooperation in handling and managing household works.
