@GalacticTurtle >seeing my body not through my own eyes and my own desires, but through the eyes and desires of others.

This is basically what people mean by body image. How they imagine others see their body. I have no idea how my body looks, I know I'm tall and skinny and I don't care how I appear to others. I mean sometimes I wonder how I look like from the outside in movement but it's not something that gives me insecurities, it's just curiosity. Having a body image at all is a sign of intense self-monitoring and dissociation.
