If you haven't eaten lunch or are curious as to how an 'outie' gets turned into an 'innie', you can check out these videos of a gender reconfiguration surgery (or GRS for short).
WARNING: These videos will be fairly graphic, so if you have a weak constitution or just ate, these aren't the video clips for you. You may want to wait until you get home to see this one if you're at work. Minors need to get parental permission to see them.
