I can't believe your wife prefers the Gixxer over the Ducati. My wife adores the looks of my bike, and Ducati superbikes overall. She thinks they are the prettiest on the street. I have to agree with her. 
You have to be happy with your bike. If the feel is not right and it's too much power for your use, then you're better off selling it.
