Wifey Material...

I just over heard a conversation between two young ladies ranging between the ages of 22 & 29. One spoke on the importance of sexual intimacy prior to marriage. In today's society it seems as if women prefer for the man to milk the cow before buying it...(if you know what I mean) Does pre marital sex hinder or enhance the chances of tying the knot. Define the qualities that a man looks for in a woman whom he deems "wifey material".
