Can you give some tips for intercourse as i am newly married and need a child.

It comes naturally: If you are ejaculating in her vagina, you are doing what you need in order to become a father. Really, in spite of much discussion, there is no magical technique for intercourse that will make conception more likely. I hope also that you want, rather feel that you "need", to become parents. Best wishes, and i hope that the two of you get what you want.
