Isn't it time for "Female Husbands & Male Wives" ? women have advanced themselves in all ways.. so why not?

you mean evolution changed it that way? or are you imposing?

evolution is all about the survival of the fittest. There was a time in our evolution where it made sense for our survival to have man the hunter and woman at home looking after the domestic duties. But i think we have evolved way beyond that and now it is a question of a good, happy, succesful marrage. To impose old fashioned social norms in this day and age is a recipe for a disastrious marrage....

but i defy a man to have the same maternal instincts as a woman...:)

That's just branding using old scriptures. Its basically the opportunity. I got the opportunity to raise my twin sons and I got all the maternal instincts. Its like saying only men can gain driving skills, by never letting women try it.
