Duchess First off, un-Mumsnetty hugs.
I will probably be flamed for this post.
I actually know pretty well what it feels like to live with someone "gender confused", I don't think I have ever felt so self-conscious since DP told me, although he told me months after we got together, fortunately not years.
He also told me he didn't want the op and just wanted to dress up a bit so being 18 at the time I decided "okay, I can live with that", wrong! A few months later after experimenting with clothes and such he decided he might actually want the op, I tried to live with it and couldn't and went in a bit of a downward spiral, I told him that I would only stay with him if he promised he would never go public or get the op as if we had children and years down the line he changed his mind, I could not put them through the humiliation of that and would use this to push for him to have no contact, at least in public.
Eventually he chose me instead of another gender and hasn't in 2 years even mentioned it again and no longer dresses up etc, we now have a DS.
Something I really hate, is people who decide to finally tell their partners years down the line and really leave them with no choice. My mind was made up when I met a TS in a gay bar in town while with a TV friend and he was in his mid 40's and was telling us how he finally "came out" to his wife a couple of years back because "he couldn't live like that any longer", he chose dressing as a woman over his marriage and kids and left them. :(
I do believe that it is a real condition and that some can really be born in the wrong body however if that was simply it then surely acting like a woman and being accepted by the other half as that would be enough, genitals and make up (wtf? plenty of women don't even wear make up) are only aesthetics.
I was born in a body that doesn't work properly, I am in agony and exhausted every single day. Would I choose a cure over my family? Would I hell.
