My wife don't like smooching.

Hi Everyone,
We are married since 2008 and we have one kid. We are good and happy and we are trying for another kid for a longtime. We use to have sex   2-3 times a week but my wife doesn't like to smooch also she never did a BJ. Is there something that I am missing. I requested many times and she is not interested but I feel depressed sometimes. Is there something that I should do.
