If you are born male you have a male body shape. If you are born female you have a female body shape. This is defined by the fact you are either born male or female and the different structure of those bodies are designed that way for different purposes. This is why male/female sex is designed to produce children and male/male or female/female sex does not. And why male/male sex has to resort to putting things up body parts which are designed to be an exit route only. Just because you want to be a man does not make you have a male body. And vice versa. I am sure in your little world if you think you are a cheeseburger you will demand everyone else treat you as if you are but .. and listen in here because this bit is important .. It doesn't make you actually look like a cheeseburger.
