It would be nice not to have boobs anymore and to be able to look good in all of the clothes I want without having to adjust things >>. Also, penis. I'm pretty sure I want one. And no periods? Fuckyes.
But as for the gender thing? I'm a girl. Female. And I don't really have a problem with who I am, I just have aesthetic preferences and things I'd like to change about my body like anybody else.
