To me, writing is much freer than dancing. With writing, you could do it whenever you wanted. You didn't have to do little exercises and stay in shape. You could have great moments of inspiration that advanced the story. In dance, unless you're going to choreograph things yourself, you're at the service of someone else.
If you look at most women's writing, women writers will describe women differently from the way male writers describe women. The details that go into a woman writer's description of a female character are, perhaps, a little more judgmental. They're looking for certain things, because they know what women do to look a certain way.
