I was born male, but I feel like doing and being female, but I still enjoy boyish things, just as well as feminine. What am I?

Your gender is entirely defined by how you feel, how you see and perceive yourself. "Boyish" and "girlish" things are arbitrary definitions fixed by a certain society: a man who wears a skirt is still a man if that's how he feels, regardless of what society says. And in fact, in some societies such as the Scottish one it's acceptable for men to wear some sort of skirt. It shows that masculine and feminine are realty arbitrary concepts. Your gender isn't based on what your style, preferences, behaviors are. If you feel woman, that's who you are, and whichever thing you enjoy will not change that.
