you can't change your history, no matter what kind of self mutilation you engage in. Neither can you change your DNA.
Sorry , but if you were one of my relatives you would still be He and your given name would be the one used.
There is no reason on earth anyone should treat you as anything other then what you 'are' regardless of what you image you want to be'.
A man who has had a sex change operation is still a _man_ who has had an operation to make him appear to be something else, not a woman. No matter how elaborate the self mutilation or custom you wear you can't escape the reality of what you are.
In the same way, you can have a full body hair transplant and spend your whole life in the jungle with a group of gorilla's even taking one as your mate , but you will not be a gorilla.
