First of all I think it is wonderful that you are taking this step to find out what you can do to help her feel more comfortable.
I have to say that I agree with what the other wonderful ladies have said, it is all about the little things. Whether it is buying a single rose and leaving it on her pillow or night stand, or My husband went as far as to right I love you in soap on our bathroom mirror. They may seem silly but they count. Your wife has feelings that so many of us do, and it is a hard thing to deal with in the day in age when everything else is based on beauty. So by you doing the little things for her it shows that one you are thinking of her and two that you care about how she feels.
I am sorry if that doesn't make sense or is just rambling. I hope it helps.
