As I have mentioned in a couple other threads here recently, dancing is a big part of my joy right now, and I often when I do it, it is so beautiful to me. As a male, I appeared rather spastic, but as a female that has changed. I find that the high heels I use are rather limiting, but you need to get as comfortable as you can with them. Don't try to get fancy with the steps, girls are not expected to be that fancy in heels. Find a simple pattern of movement and just vary it slightly. For me, dancing like a girl is all about fluidity of movement. I think of my arms as being like water running over rocks down a mountain stream. Let them just flow, and really get into the music. Feel it with all your heart and soul and don't worry about how you look. It will be magical if you let it.
