Males and females are born with physical differences. Men and women have a lot of different things such as playing, specking and thinking etc...

 Some time it is difficult for me to understand women maybe that because we have different thinking way. I have an example: when I feel sad or angry I want to sleep or be alone. However my wife wants to go outside to refresh her mode. I believe men and women use language differently because usually men like to be leaders and they like to give orders but most women interesting about how they look like and for fashion.

There is more than one way to communicate to each other.

Finally, I think each culture has its own way of defining gender.
