IAmA young lady with XY Gonadal Dysgenesis. AMA!
The Wikipedia page above explains my condition should you wish to know more.
Basically: When I was still in the womb, the forces that be decided that I would be a male, and at some point they changed their mind leaving a perfect baby girl on the exterior, but internally I didn't grow a complete reproductive system.
I had an operation to remove what should have been my ovaries a few years ago and now I take hormones for my mental and physical health.
I searched and found another AMA, but this woman found out much earlier than I did that she had this syndrome, while I found out when I was a young adult.
TLDR: I'm a mutant, ask me anything.
EDIT: Here's my proof. http://imgur.com/a/Fb3UD (Yes! I'm terribly computer illiterate and edited those pictures on Facebook. What's a gal to do?)
The pictures in question are of my keyhole surgery scars. They are faded with age, so I circled three of them for you, the other is inside my belly button. The one above my belly button is from an infected belly ring. I don't recommend it.
The other is of some hormone meds I had to take for a while that turned me into someone I don't like. I lost a lot of weight while on them, because they made my stomach feel disgusting most of the time.
