Jonathan, I wouldn't assume that she wanted to talk about the grocery list or whatever, but what if she needs talking to maintain the connection to you? Maybe the silence is too much for her...it proves (in her mind) that you are all about the sex and physical release because you are not interacting with HER. Now, I like dirty talk during sex...your wife would probably not go for that, but I think you could accomodate her need for verbal communication while still not talking about the new curtains she just bought.
For instance, you could tell her how much you love her. How pretty she is. How close you feel to her. That she is everything to you. How good she feels. That you could do this forever. Ask her questions, for a change in pace: Do you like it fast like this, or slower like this?
In other words, engage her in the process. She might NEED this to really get a lot out of the session and you might have to deliver this, even though you'd rather be quiet and enjoy the moment. Give and take, that's what it's all about and I know you'd give her anything she wished for, if it would help her enjoy sex more!
What I am trying to convey is that maybe you misunderstood her need for more communication during sex? It is worth exploring, when you finally do smash the Six Year Drought all to bits.
