Who am I?

"Today, I am 20 years old now. I still don't know my gender. From my look and my birth certificate, I am a male. However, there have not been one day when I feel like a male. I like girl things. I envy those girls who can wear pretty dresses and long socks. I like these things too, but I can only wear it secretly and sometimes I even ashamed for it. I think I am a transgender woman, so they called shemale or tranny. I hate the name and I also hate to be a transgender woman. I am very confused." This is said by a friend of mine.
