Every man fears one thing most!, post marriage freedom phobia, probably one reason that men wants to extend their knots must be due to this,i guess, another reason must be probably women folks have become more sophisticated.. or their atttude towards life has been considerably changed due to many factors or their upbrinin.

I remember a dilogue from a movie "Pillow talk " ... Before marriage, a man is just like a Big tree in the middle of a forest with its leaves stretched out, & independent, flowin with the tunes of motion, & the time comes when it is chopped down, and thrown in to piles of logs, & is made in to a vanity table, or a baby crib... a stage of transformation indeed
In short, Men wants freedom and often women fails to understand this.They fail to understand the psyche of man,
many people say.. its hard to penetrate the mind of a women.. But it is easy to know how a man is, true to an extend. However, man is an compressed incontrollable emotional being..
many men think.. that showing emotional feelins tends to make them not a Man, men tends to be more physically attached where as women is more of emotional, the diffrence in these attributes often conflict or many a times have an unbalanced.
Creating a +ve sense of understanding between, or building upon a strong foundations of love & respect, a certain level of ambiguity can be erased of.
