I have less experience than my wife, so my opinion isn't worth expressing?

My wife is 11 years old than I am (I'm 32, and she's 43), and we've been married for 1.5 years while knowing each other for about 6. The age difference works out okay because I'm slightly mature for my age and she looks/acts pretty lively/youthful (we meet about halfway haha). We have a difference of opinions I'm hurt but puzzled by. She confident, aggressive, extremely popular, married once before (husband got into drugs), socially skilled, and has been through many relationships. I'm neither very confident nor very popular/socially skilled, and she's the first real relationship (beyond 3 months) I've ever had. She has no respect for or desire to understand my opinions on relationship issues because she says I have no experience base for my opinions. My stance is that 1) a marriage is supposed to be a equal partnership and 2) I don't need experience to have an opinion for what/how things should be done. I do tend to be slightly idealistic. Her lack of respect (as I call it) really makes me feel like a little kid, like I'm married to my parents. What should I do? Thanks!
