How far should a man go to give a woman what she wants in the bedroom?

My wife recently made it clear to me she has interests in the bedroom that go beyond my own fairly mild ones. She hasn't flat out said it, but she told me what she thought about and typically dreamed about, but they are things that are kind of out there by comparison to what I'm used to. How far should you go to accommodate those interests? I worry that we met young and had little outside experience, though she had a lot more than me. Is there a risk if you fail to go far enough, or alternatively if you go too far so that it harms your marriage? We've been together for almost 10 years and I value our otherwise great marriage.
