We all wanna marry a woman/man who know us but what if we marry a stranger. When a new relationship start with stranger and first day on Bed. This is really strange this that two stranger spend first day or night on bed. 
I have a heard story where a man didn't start his life on bed first day after marriage. He said, first we know each other and than we do everything. 
I don't know if it is happen in real life.
