I would agree that it would be odd to assert that people treat you like something you physically aren't, but you're missing the point which is the way you view yourself, not the way other people view you.

You are free to have whatever self image you like. >>I've always imagined myself with large boobs, and look, I now have them to fit my self-image, so I consider them part of myself.

That's not asking anything of anyone else, and yes it's totally OK to be whatever shape you like (I'd prefer to be healthy myself) - Naomi's girlfriend seems to prefer not to be hyper-feminine and that's fine too.
