I have to say that I slept during biology and health

, so I’m interested in the scientific aspect of gender issues. I admit it’s embarassing, but when everyone talks about XX, XY, XXY chromosomes, mixed body parts, etc. I’m pretty lost. From there I would like to move on to the effect that it has on people that are dealing with these complex issues.
I have to tell you that when I read one person’s story I was speechless. The emotional toll it had on her, the cultural stigma attached and the unloving, sometimes violent way that she was treated astounded me. I just didn’t know that there were people who dealt with this kind of life. In her case, she was born a male, felt like a female trapped in a man’s body and so had a sex change operation (a transsexual MTF, I suppose).
There seem to be so many complex issues and definitions that it’s mind-boggling to me. So, I guess I’m looking for the “Dummies Guide To Gender Identity”, I suppose. I hope my understanding and questions are not offensive. I don’t intend them to be. I’m just surprised that I knew enough about anatomy and reproduction to have kids
Thanks again.
