I think it is about passing. It's about making the outside match the inside. I have had trans people say to me "you can't say its about looking female, you are not doing it for that reason" or "it don't matter if you still look like a man, as you will feel female inside" Stupid!!
But, I already feel female inside (reason why I am changing my gender), but I still look like a man in ladies clothes.
If I should not be doing this to change my body to a females, then I may of well not of spent £2000 at a clinic or had any HRT at all!!
If there are any people on here who don't really mind if they don't pass or feel that it should NOT be about passing then thats fine, but I am sure that for most trans people, they say they want to be able to pass like a born female or born male.
