Hi,
Every woman is different when it comes to the things she likes in bed. You have to remember to always be considerate and try and understand, or better yet feel, what you wife like best.
If your wife doesn't like you starting with her breasts, try and find out what it is she does like. communication is very important here and don't be afraid to ask your wife to tell you what she prefers. You'll find that it'll make things easier.
