Just to add, given the current state of my hormones -- I find it deeply insulting for anyone to suggest that bags of silicone under the skin of your chest is equivalent to my breasts. I may have never lactated and used them to feed a child (functional secondary sexual characteristics), but I think they probably would be functional if I had ever needed them to be. Just as artificially altering hormone levels isn't equivalent to what my hormones do, because a male doesn't have the bodily organs that those hormones act on. So, it isn't just mood changes and irritability or whatever other actions on the brain you are hoping to achieve, a male, whatever surgery or hormones, will never have a womb that bleeds as a result of those hormones. Will never be hoping for a child, and then disappointed to discover that there isn't one.
This is what I share with those other women here on Mumsnet, in the bone and the blood, and it matters. How dare they say that it doesn't, or that a feeling in the head, or a superficial simulacrum of our bodily functions is equivalent. And to all those who claim we all just go to the loo to pee or poo -- you can tell right away that was written by an actual or wannabe male, because the bodily truth is that most of us spend an awful lot of time in the ladies dealing with the messy business of menstruation.
A womans right to bleed, and deal with it only in the presence of others who either do, have done, or always expected to do the same. Not those who never did, never will, and never expected to, because they are not functionally female in any way.
