In many cultures, it is accepted for younger women to marry older men... There are many reasons... Firstly, as someone previously stated , it is do with child bearing..

Also, generaly, women tend to "mature" earlier then men.

I even read one article which said that older men like to marry younger women, because they can be easily "moulded"..(Not set in their ways)

As far as your posting, it is becoming more acceptable for older women to marry "toy boys" , specially in the West..

The problem to me is that younger men usually "think with their pecker".. If the woman is much older, then he may start looking elsewhere if she cannot meet his needs or begins to look too much older than him.
